What kind of cement will bond the plastic in the interior of our cars. For Example... My rear strut cover comes off because one of the plastic rectangles that hold the cover's clips is half way broken( a shread of plastic holds it on ) I have tried model cement , Super glue type cements, pipe cement ( used to join PVC piping ) and some other 2 part epoxy. Nothing I have seems to fuse to or melt the interiors plastic. It seems like it's too slippery to cement to.


Any clues on this one. I know there are a lot of smart people on this forum...


Thanks,

Use a plastic knife and a lighter then.......

Super glue should have worked......

 

Niether super glue or super glue gel held at all they both just flaked off.

Can't bond unlike plastics. I did consider using a soldering iron to try to remelt. Not sure if this is a thermo set plastic.

 

GOOP!

 

They make junk that bonds plastic... epoxy... I KNOW that someone had a post about repairing the plastic headlamp covers on this forum about a month or two back.. do a search for that thread.

 

I'm pretty sure the plastic that the head light covers are mad of is different than the rear cargo area plastic. I tried 2 epoxies one I got from work and some 3M stuff I had here at home, I have a lot of glue. Don't anyone suggest that I try elmers either...

 

GO ELMERS!! haha

 

Theres some stuff that they used to use at my moms work it was called M.E.K but they don't make it anymore to toxic I believe. I just asked her, she works at a place that makes stuff for planes.

 

Had the same thing happen to me with some panels. Here is what I did to glue the tab back on. There is a glue called Zap that you can get at most hobby stores, it's basically crazy glue. I used that to stick the parts together. After that, I used 5min 2 part epoxy to surround the base to make sure everything holds. Seems to work so far.

 

MEK is Methol Etcol Ketone, and yes its toxic, but I have never heard of it making things stick together, we used it for cleaning off paint...

 

What about JB Weld?? It is strong yet sandable and paintable as well. The only draw back is that it takes longer to set up.

 

how about model glue?

 

JB weld is good for metal, I have never tried it on plastic, probably has the same effect as most epoxies..

 

JB weld is good for just about anything. It will hold just about ANYTHING together...

 

really? I will have to check it out...

We have it but, I have never tried it on plastic, granted I dont work on very many things that are plastic...haha

 

two part clear epoxy available at the hardware store...that stuff rocks

 

I would try the two part clear epoxy. Prematex and Devcon both make good ones. Something like a 2 ton shear strength. Give them a try, Tom

 

For those who don't read from the top of the thread....

I have tried epoxy, both clear and with metal filler, I tried model glue, i've tried super glues ( runny type and gel ) I have tried PVC pipe glue, I did not try any of the wood type glues ( gorilla, elmers ) I have not tried silicon based adhesives or liquid nails. because I felt none of these had a chance of holding when the others just peeled off. I thought of JB weld and I have 3 other simular epoxy putty ( for various materals ) but you usually have to build up a bunch of it to hold and would look like crap. I guess I could scrape a piece of the plastic off and bring it into my lab and figure out what type of plastic it is and look up what it's solvents are and work up my own "glue" but I thought someone would have repaired this stuff before and could point me in the right direction quicker.

This plastiv is not like the dash (harder) but it is not like the panels that chips paint( door handle area, center consol ) this plastic is harder and model cement would probably work on it. The rear plastic parts feel "greasier" ans this is not from armor all. it is the plastic itself and the reason why I think nothing is sticking to the stuff.

Thanks for the replies so far.

Sorry RX7FAN, I missed that you tried all these already.
Hmmm....... what about one of those plastic welders. I thought about buying one to use on my motorcycle fairings. They are kind of like an iron and you heat the plastic up, then there are different types of plastic rod you feed through the iron. It leaves a bead on the back surface you are repairing like a weld bead. I looked at one about a year ago, found a great site that specialized in them. I think I just searched on plastic welder. If you can't find it, let me know and I will see if I can locate the site again. Good luck, Tom

 

Duct tape... it fixes everything

 

Duck tape... good greif. they call that stuff West Virginia Chrome around here.

I just tried something new, don't think it will work though. I found a bottle of Contact cement. It has toluene and some type of methyl chloride in it. Sounded like it might dissolve something. I'll know in a half hour.
