Super Glue-Gel for filler?

Several weeks ago I removed a couple gnarly patches on my rear wheel flares using a heat gun and plastic razor-like blades, and in doing so I gouged-out a small chunk of material creating a crater. I have procured the correct touchup paint and a can of Dupli-Color Plastic Adhesion Promoter for the job and I've been wondering about the filler for that one little crater. Somewhere, beats me where, I heard you can use super glue to fill little craters. Because it is on a vertical surface, I have moved to super glue gel for its ability to stick without flowing as gravity plays on it. What is the consensus here, will this work as planned? Does super glue gel meet the requirements and weather-worthiness that is needed for this purpose? Of course it will eventually be sanded and painted to match its surrounding area.

 

Have a similar situation

 

Don’t do that. It’ll f it all up. How deep is the gouge?

 

No more than 1/8" deep. Curious as to why you state it will F it up? The cheap-ask Scot in me doesn't want to buy a filler, as they are sold in such a large size for my tiny needs, and I have a new tube of SG-gel.

 

I would do a bondo putty type product for plastics...good to see you’re getting on the projects!! Good luck Tundra brother.

 

Because it’s not the right tool for the job. Superglue doesn’t dry uniformly, nor can you say what the ability to sand and finish it is if You need to. Just get something like this. It isn’t expensive.

FWIW. I used epoxy and let it cure for a day clamped and the crack came right back. Super glue ain't going to stick

 

Ha, ha! FWIW...I asked the question after applying super glue gel about four days ago. It has hardened, shrunk, and appears permanent; I would have to chip it out of the crater were I to go with another filler (not that I am opposed to that, should a better alternative present itself). Now before anyone says I put the cart before the horse, which appears so, I went with what I had read previously and only today have examined the outcome and noticing the shrinkage. I'm not too happy with the SG-gel and I'll probably remove it and use another filler, but I am waiting on advice to form my plan to proceed. So far the advice given by Rubberdown sits well with me, though I am still fence sitting for the moment.

Even with the web's help, I am still at a loss as to the flare's material of construction - is it polyurethane, or what. I spent many hours over two days searching this out and getting nowhere, and that, plus the previous info alluded to about using super glue, decided me to go that route. What successfully bonds with what, and what is it I am trying to bond to? Cat chasing it tail comes to mind.

 

Yea, sometimes I look for the originals and then the cost of painting. Hell might as well buy 4 new ones cuz you can only buy the set unless you get lucky at the junk yard You're going to have to spend serious ass time on screwing around with it to be perfect. It's a replaceable plastic part.

 

I would go with JB Weld over Superglue gel. If you mix the JB Weld just right you may be able to match the truck color

 

Maybe you can just use some spot putty / glaze for filler then sand it? It's cheap at about $5.00. Not sure if this is only for small pinholes or if it can also be used in larger chips/gouges like yours. Maybe others can chime in on that.

• Great for filling pinholes in body filler
• Can be sanded and painted

Bondo Glazing & Spot Putty
Bondo Glazing & Spot Putty is easy to use, dries fast and stays durable without shrinking, ideal for filling pinholes in body filler and covering auto body scratches, paint chips and minor dings. This 1-part nitrocellulose putty dispenses easily and efficiently right from the tube with no mixing, affords a 3-minute working time and is sandable in 30 minutes for fast, efficient repairs.

Big Benefits for Smaller Auto Repairs
Applied directly from its easy dispensing tube, Bondo Glazing & Spot Putty is formulated for quality auto body repairs in less time. Its 1-part nitrocellulose formula eliminates mixing and helps to keep small vehicle repairs simple, efficient and on schedule. Unlike many 2-part putties which can require longer to dry, Bondo Glazing & Spot Putty is sandable in as little as 30 minutes. It is non-staining, so it won’t affect the color of paint or finishes around the repair area. It also shrinks very little over time, helping to ensure lasting repairs without rework.

 

So far three possible candidates...but how well do they adhere to polywhatever plastic? Or is it ABS? That is also why I went with the super glue, as I knew from experience that it will bond with all the plastics I can recall using it on.

Hmmm...While typing the above, it occurred to me that I have another glue sitting in my freezer that has super qualities and bonds to about anything and that is Aquaseal, a urethane glue that cures almost diluted milk colored. Question is, can it be sanded? Will it take paint? I think I will thaw it out and do a test to determine both answers, while mulling over the suggestions you guys have given me.

 

It seems that it may NOT be the answer I am looking for...

It is not recommended for body filler to be applied over plastic bumper covers. Most bumper covers are made from a thermo plastic TPO or PP. This type of plastic has a problem with things adhering well. Body filler is designed for steel, galvanized steel, zinc coated steel, SMC, fiberglass, and aluminum..

Of course they are talking about bumper covers, but I wonder if it is applicable to the wheel flare. Again, not knowing its material composition make it hard to feel confident about the choice one has before them.

 

JB Weld may have an answer for plastic...

But if it is an epoxy...? Someone, 7.62Tundra I think, suggested epoxies don't work well. Hmm. Still this may be the one I am looking for, though it would be nice if there was someone to vouch for it before I commit. One saving grace for me - it is a very small area that needs filling, so if one way doesn't work it won't be too difficult to reset and change to another material.

 

You may be ok with the epoxy. My point was that it wouldn't bond a crack. It seems to have adhered to the surface pretty well. Here's a write up on the JB QUick Weld.

Thanks for the tip and the link. I read the review and it does sound promising, but there was no answer provided for my unspoken question of how does this epoxy hold up in an outside environment where it can rain off and on for 6 months or more? I plan to look a little deeper to see if I can get some word on whether or not it is waterproof.

 

Sleepless, I spent about 5 hours pre-dawn looking for info on the super glue being used as a filler in minor auto body correction and finding none. Oh, it is a great filler for wood and plastic and porcelain, so long as its indoors. But even Loctite dot com walked a fine path around waterproof, while saying it is water resistant. I need more than that, I need an assurance that it is waterproof when used per my plan. It doesn't look like it is up to snuff, but I did email Loctite's consumer division seeking an answer to my questions. It would be so easy to use that gel, as it is half filled already and needing one last fill and screed to be ready for sanding. Hopefully by early next week I will have settled on choices #2 and #3 while expecting word from Loctite on #1.

In the meantime I have a full set of wheels that need some serious denastification* and paint.


*I just coined the word denastification, the act of making something less nasty, and I claim all copyrights. Should you wish to use the word in the future please send me an email so we may talk about the royalties. Be prepared by bringing some big bucks to the table. I sense the need for a new turbocharger.

 

I haven't used the JB Weld for plastic but I did use some JB Weld regular on a 1990 Honda Fourtrax rear axle and hub where the splines were starting to strip. It held up great in the mud and water. When I needed to take the hub off 15 years later I had to use a torch to heat the hub and melt the JB Weld to get the hub off.

 

Found this for super glue being used as a filler. Seems like it is used but the trick is using baking soda on it.

I believe the baking soda simply quickens the "set" time to minutes. Seems to have quite a following for indoor projects.

Super glue gel alone, when applied to an exterior surface exposed to weather (rain) seems to hold up well, but it shrinks a fair amount and cracks far too much. Although the depression I wish to fill is small, the shrinkage makes the gel a non-contender. I will be going with J-B Weld Plastic Bonder as it works with various plastics. Just waiting for the rains to stop and temps to rise above the mid to high 40s.

He said is friend repairs helicopter blades using that technique. Sandable too

 

I'm sure it works fine in that application where shrinkage may not be a concern. The problem I see, and which has been addressed in my research, is the shrinkage. Whereas visual appeal may not matter to the helicopter blades, it does matter a great deal in body work. I would be remiss were I to use a filler that shrunk after all the sanding priming, painting, etc., leaving the telltale visual of the patch. Therein lies the appeal of the Plastic Bonder which is reported to have next to no shrinkage. Apply, and finish, knowing it will blend in.

 

Understand. I just ran across the vid and remembered your thread. It's an interesting trick that I'll put in my files for the next time I try to fix something.

 

Use a plastic bumper repair or filler

If you lived closer, then I’d gladly turn you on to a squirt of some organic based 2-part epoxy that would work perfectly. It bonds to anything, tools nicely, and contracts/expands with all/any substrates. Only drawback is that it doesn’t sand easily like Bondo, but if you are good with your hands and have the proper technique/tools it doesn’t need sanding.

I’d post the product, but the buy-in for the product and special applicator gun is not feasible for a one time use.

 

@SoCalPaul ...Yes. As noted above in tan color. Your's being the same in black.

 

@Professional Hand Model ...Thanks Fred, but I have it covered. Just waiting for a change in the weather.
