Safely remove old paint from plastic.
 

I have a real, original GM flapper valve assembly for 69 ZL2 hood.

I have owned this part since 1983 when I traded for it. Very good condition. The steel frame is easy to clean up. Sand blast cabinet.

However, the original "M" embossed Monsanto flapper is covered in orange and white paint. Yes, it came off a pace car that someone painted without removing the flapper assy.

Most of the paint will peel off with a thumbnail, but frankly, I don't want to spend three hours cleaning it.

Anything I can soak it it that will not hurt the plastic? I am guessing it is abs, but who knows.

I personally would use plastic media at low pressure. A soak in power purple/castrol super clean would work to. See some of NJSteve's posts for the power purple insight.

I had some of my interior underdash plastics in my 70GTX soda [powder] blasted with great effect. The plastics were painted in 2pak and all was removed without damaging the grain in any way. As Jason said, the guy used lower pressure, it took all of 20 mins. The plastics are not repop'd in FK5 Orange.I was more than a little paranoid about using caustic or oven products. With the soda blast they turned out really nice, good as new- literally! Dash pad,arm rests and console next!..Yes they painted all the orig FK5 pieces to "freshen-up" the interior.. DOH!!

cheers Dave

Oh me, oh my!

I wouldn't be blasting anything. Easyoff will remove the paint and not harm the plastics.

Agree with the Easyoff method.Especially the bio degradeable stuff.
You can control how deep you want to go by how gradually long you let it sit,then rinse off with water.

Yes, the Purple Stuff degreaser will wash that overspray away in a matter of minutes. It doesn't hurt the plastic either. It is what all the plastic model guys use to remove old paint. It breaks the bond between the paint and the plastic surface and the paint just falls off in flakes. It is better than Easyoff oven cleaner as it does not have any propellants that can craze the plastic.

Lynn, I'm a painter by trade. I don't normally take paint off of plastics but there is a product called GOOF OFF. If you have some take a lint free rag and do a test spot in an inconspicuous place first before doing the rest of the plastic. DO NOT soak the part. May take some elbow grease but it should work.
