POR is an epoxy putty mentioned earlier in this thread:

I would think it would be similar

no... por-15 is for metal.... it will dry hard as a rock & have no flexability at all.... not compatable really.....

the idea is to use a material that is consitant with, & has the same basic propertys of the panel your working on..... that's why bondo is bad for a job like this & can crack..... you want similar flexability & expansion/contraction in hot & cold extremes....

That settles it for me - dynatron bumper repair kit, here I come..

Thanks for all the info turbocad

after reading all this i've convinced myself i'm going to give it a go but i've got 2 little snaggetts one is the suround in my car has got PP+E/P on the back, now is this just polywhatshisname or is it something else? secondly i got another front for my linitx screen and the only marking on that is SEFORM is that a type of plastic or just a name off the people that moulded it?

Found this....

could work better & cheaper than legos or grinding up pipes. It also looks to be colorless... unless they are painted, which i doubt.

So I got halfway into this process, and had spent so much time trying to find ABS and get the sludge made properly, and get my dash cut and screen epoxied in place and prepared for ABS gooping, that I never took the time to check if the material of the console it was going into was soluble in acetone...

so now I've got everything all set to start squirting on the plastic, and the plastic won't bond to the console. I'm debating whether to go for it anyway, since the thing shouldn't suffer any serious stresses while mounted, so between the epoxy, the stiffness of the plastic, and the bondo and paint and whatever else I finish it with, I hope it will stay together.

barring that, anyone have any suggestions for other solvents I could try? I figured that if I can find a solvent that can handle both plastics, then I can simply make some new sludge with that instead. Acetone and paint thinner are both out (all I had to test with)... I also tried smearing on some PVC cement that I have, which is MEK based, and that didnt' seem to affect the console plastic either. I'm not sure how many other choices I have, I didn't really take stock of what they had to offer at home depot, but I know there isn't a massive selection. but are there any other common solvents i should look for?

My dash isn't abs, it's talc reinforced polypropelene (sic?). I ended up using raycrete, a non-toxic two part polyurethane glue that worked great.

Even though it's a glue, it works more like an epoxy. Has a long working time and it gradually becomes thicker allowing it to be worked really easily.

I've got some caveats about painting, they're in that linked post.

rather than starting a new thread thought i'd stick (no punn intended) it here. over the last couple of days i've been at a model engineering show and there was a firm selling glues, there web site is http://www.fivestardistribution.com/ please all have a look and let me know if there is anything of use as i'm not 100% sure of what sticks what perhaps theres people here more into plastics than i am.
