Hello everyone,
I have a 2004 Lexus GS300 that I am looking to do a paint job on. I'm new to doing full car paint jobs for sure, but I've done a lot of research and with the help of some amazing people on this site I think I've got my process for car prep down. Here it is:
1. Start block sanding with 180 grit.
2. Then move to 240 grit.
3. Then move to 320 grit.
4. Then move to 400 grit wet sand.
5. wash the car, remove all oils, solvents etc. After this apply primer that will stick to bare metal.
6. now apply basecoat.
Question is, I assume the process is a little different for plastic parts. My car still has all the factory paint on it, just awful clear coat damage. Would I be fine just scuffing the plastic parts with 800 then 1000 grit, so I am creating a good surface for the next coat to adhere to?
And if so - after scuffing would I apply primer first and then basecoat, just like the metal parts? Or basecoat directly?
For reference, here is the urethane primer I will be using - Kirker Black Diamond Low VOC Urethane Primer 2K Gray.
