I'm sure you have seen on your truck, the interior panels turning into a white, chalky, degrading heap in front of your eyes. You can scratch chunks out with a fingernail. I think they were made from a soybean base.
Besides making new with 3-D printing, is there a way to seal the dusty plastic, and then "fill" in the scratches, and get ready for SEM interior paint?
Or are we just SOL?

 

Heat Gun. It will bring the oil back to the surface. It does a great job on the exterior plastic too.

You ever see the jeep flares turn gray? 2 min a pice with a heat gun has them nice and shiny black again

 

Although the heat gun works great for discolored plastic parts, fender flares, etc, it's not the solution for the problem he has.

I have the same problem.. where it seems that this stuff is just cracking and falling off, or breaking into a powder. From what I've seen others do, Most sand it down and prep and paint. There are a few posts on these forums where people have redone their panels and they look pretty good...

Once I get a few other things done to my truck, I'll be tackling it myself...

 

Mine were blue originally, they were tan when I bought the truck from the same problem. I took a soft wire brush and brushed them all clean, back down to blue. cleaned them up then painted them back with the Duplicolor vinyl and fabric paint. Stuff is OK but it's chipping off in places. I guess I'll re do them sometime with SEM.

 

You need more than good paint - there's also an adhesion promoter, it softens the plastic which allows the paint to stick better.

 

Thanks for the tip!
