Prep before paint job

Hello I have a 91 buick regal and I want to get a new paint job. Overall the current paint is in good shape, it is just covered in swirly scratches, and a some fading because of the Houston sun. I plan on filling in the minor dents and finishing with primer, sand it with 400 grit sandpaper. To save money I will remove all emblems/accessories and tape up everything that should not be painted. My question is what should I do with the rest of the body? Scuff it with 400 grit paper? prime it?(all I have is spray can type)....Any other prep before turning in the car? Thanks in advance for any help.

No, do not apply anything over the remaining portion of the car. This may cause more work for the painter. First, repair your minor body damage and prime the repair areas only. Next, sand the entire vehicle with 400 grit sandpaper. Spend extra time on edges and hard-to-reach areas. If paint is going to peel, it going to start peeling from the edges. Next, use a 3M maroon scuff pad to scuff the car once again. this will assure edges and hard-to-get areas are sand thoroughly to provide proper adhesion. Next, use a spray can self-etching primer to prime any metal exposed areas. Only use on areas that sanded through. Now you ready to paint. Some paints brands recommend a sealer and other paint right over the prepared substrate.

With that said, you will not need to prime the remaining portions of the car. Just make sure that it's sanded good.

I hope this helps. Good Luck!

600 wet can be used for prep as well.

Typically though, I like wetsanding before masking up. Water is always present where you think it isn't.
And water+Paint=Fail.
