im painting my car soon, and im wondering, when u use primer over clearcoat, will it stick? do you have to sand off all the primer down to basecoat, or just scuff it up a little bit to allow the primer to stick? thanks in advance

Scuffing is never really a great idea. Don't cut corners when you are painting you don't want to do it over and over again. The best way is to sand down all of the old clearcoat and color to the orignal primer/ raw body parts and paint it right the first time it will last a lot longer and look better if you take the time to do it right you will regret it when you don't and your new paint starts cracking and pealing because you have 20 layers of paint on plastic and fiberglass body parts there are a lot of people on pennocks that know a ton about painting and a lot of great info in the search feature! Good luck

Talk to "tha driver" and "rogergarrison" they both helped me with the paint on my car they really know there stuff good luck with your painting and be patiant! Haha
The real issue is what else is on the paint. There could be any number of contaminants that will fish eye the paint.
If you were a professional shop doing a total restore, sure, take it down to bare metal (plastic). However, you don't need to. Clear coat is a type of paint. But, there are different types of clear coat. Lacquer, acrylic, etc. Sanding through the clear is a good idea. But, first, get a can of Norton Cleaner and clean it off to get any wax or other stuff out of the finish. Then do a wet sand.
You don't need to really scuff it. An orbital sander with wet/dry 400 grit emery will do a nice job of smoothing and prepping. If I were doing it I would use a good quality primer though. Do the primer, sand again and get a really smooth surface. Final sand before paint can be 400 but 600 will give a finer finish.
Good luck on it. Home paint jobs can be a bit of a pain. Remember, you will have quite alot of sanding out with 1000, and then 1500 grit before you can buff. You will undoubtedly get some orange peel, and if you aren't careful, the occasional run. All these can be wet sanded and buffed out though.

thanks a bunch guys. i have an orbital sander but i wasnt sure if i should use it since iv heard everything about a DA sander being best since it has a random pattern. ill be posting this up once im finished as an example of what a first timer will get doing everything on his/her own, excluding help from family members. yeah i will be working with orange peel/runs/trash in the paint, and buffing is gonna take a while since i have no mechanical buffer to use. if anyone in the GR area has one and would loan it to me i would greatly appreciate it thanks again for the tips.
It may help you with painting your car. This was my very first paint job and I had no experiece whatsoever painting a car. It's not hard, per say, but it is very time consuming and it will feel like the sanding will never end.
yep. i decided to post it all at once (i know ill get yelled at when i do lol) and then update a few weeks later to show how its lasted. iv been taking pictures at the end of each day, and twice today, once after some more sanding, and again after washing the car.
