Any suggestions on what kind of paint I should use on these? Will normal paint work? or shoul I get a brand of plastic paint? Any suggestions?



Thanks

Use plastic paint. Plastic primer is also available, so you could prime them first.
Why not just clean them? Any paint won't be as durable as the plastic finish.

Years ago I used Rustoleum 7777 Satin Black on some and it worked fine. Now I would use Krylon Fusion plastic paint in semi-gloss black.

They'll never hold up. The heat will cause the plastic to expand and contract thereby causing the paint to peel.

I didn't have any problem with peeling paint.

It's been about 11 years ago but if I remember right I cleaned them well with Simple Green or similar and wet sanded with 400 or 600 grit to give the paint something to grab onto. The Krylon Fusion is made for plastic so maybe sanding wouldn't be req'd but I'd read the directions.

IMO, if you must paint them, use something flexable. Use something suitable for a modern bumper cover otherwise it will crack and peel. DuPont (I think) used to have an additive called "Flexar" (again, I think. It's been a looong time since I worked at the shop where we soldand mixed DuPont paint).

I can't say for sure about prepping them, I don't know if these plastic liners are "oily" or not.

Oh, when I said "oily" I was refering to the make-up of the plastic itself. Some plastics are I guess petrolium-based which makes them very tough to paint or even glue.

Oh, BTW, when I worked for an Audi dealer, the plastic ears would ALWAYS break off the fan shrouds. This was a type of plastic that would not take to glue, so the techs would put Super Glue on both surfaces, sprinkle a little baking soda on top of the glue, and put it all together. The baking soda allowed the glue to stick to the surface. It worked every time.
