Im going to be painting my engine plastics, do yall have any tips on what type of paint i should use as well as how many coats of clear i should use to protect it from engine heat. Also do you think i should sand and primer it before i paint? thanks

Automotive paint + automotive clear.

I will be using urethane paint, and that sh*t's tough!

I'll be using a high-build primer after sanding down the plastic to get a smooth surface.

No, listen to me...

I painted mine. They look incredible.
All I did was:
Sand with 400 grit, then
Sand with 800 grit, then
Sand with 1200 grit, then
Sand with 1500 grit,
Clean with alcohol, water, and microfiber, and
Painted with 6-8 thin coats of krylon fusion (I used red)

I didn't use any clear coat, or anything. Since I did this about 16 months ago, I repeated the process about 4 months ago to get a more vibrant color.

All you have to do is clean them about once a week with some dish soap.

Well i just used a scuff pad and some prep cleaner for plastic then sprayed it with crome about six times then with a blue anadized color then a bunch of times with high temp clear. It gave it a candy blue color and it changes shades depending on how you look at it. the picture does not do it justice.

You'll need to use Bulldog Adhesion Promoter on plastics as a primer. Otherwise, any paints you use will not bond properly. You can get Bulldog at any auto parts store.

Looks nice. How does the paint stand up to engine bay heat over the long term?

No reason to use that fine of paper.

Sand 180. Adhesion promoter 5 minutes before two good coats of primer.
Sand 400. Spray base coats until uniform with around 5 minutes between coats.
Flash time for 20 minutes. Light coat of clear. 5 minute flash medium wet coat. 10 minute flash medium wet coat.
Let it cure for a day and you're ready to put it on or wet sand it if you choose.

Mine should be painted next week when my car is ready for paint, will post pics. The painters are concerned about the heat of the engine bay also. While my car is in the body shop I am having them do all the small projects to the car that I am too chicken to do, rear wing, roll the rear bumper cover, and painting the 3 covers in the engine bay.

Hit it with some 400 and use this http://www.wmbarr.com/product.aspx?catid=1&prodid=56 right before you paint them. It will be fine. I used it on mine and it has held up real good.
