We are trying to clean our headliner - some people have said to use acitone. It appears that it is messing up the surface of the plastic rather than cleaning it. Can anyone tell us why this is happening? Is that just surface gunk it is removing or is it in fact hurting it?
Your input is appreciated.

Acetone will dissolve plastic!

If I use ZDDP in a new car - will the tappets go flat?

Steve,
To clean use soap,ajax and a brush to scrub the textured surface, and rinse.
To remove discoloration use paint (spray cans, Krylon Fusion), or glue a material with 3M Super Trim Adhesive #08090, after it's cleaned.
If it's cracked, support the liner as if it's in its place and used Marine-Tex to fill the crack; use small wire or something (to loop-sow across the split)(I covered mine) reinforce at the outer lip and keep the crack from braking again when you install it.
The prosses of learning by doing.

ACK. Acetone will melt the headliner. Bad idea. I'd use any commercial cleaner, but I'd test it on a small part first. I'd be wary of any solvents. Soap, water, and a bristle brush would be the safest. Next would be Windex, then 409, then Goof-Off, in that order. Then, I'd redye it if it was still dirty.

If we are talking about the end caps then here is what I did about 8 or 9 years ago:
I removed the front end cap and placed it face down on a pair of saw horses. Then I squeezed and spring clamped the cracks together and fiber-glassed the back sides of all of the cracks. Some of the holes had become elongated and some of them cracked. I filled all of the various mounting holes with epoxy resin mixed with ground fiberglass. After it all hardened (24 hours) I ground and sanded the front (normally exposed) side flat and re-drilled the mounting holes.
Now for the paint.
I turned the cap face up, sprayed it with Simple Green, and scrubbed it with a scrub brush. Then I rinsed it thoroughly and let it dry. I did the process a second time only this time I flipped it over (face down) before rinsing it a second time. The reason for turning it upside down for rinsing was to assure that none of the rinse water and soap residue puddled during the drying process. When it was completely dry I flipped it over again and rattle can sprayed it with white fusion paint for plastic.
I have had it reinstalled for about 8 years and 40,000 miles. It still looks like the day I installed it.
So the simple answer for painting is: Scrub it with Simple Green, rinse thoroughly, and paint it with Fusion paint for plastic.
