Question on wet sanding

[luckydawg]

I have a 2015 F-150 that I know has base / clear like i think all modern vehicles do, not aware of any that are produced any other way. I have used 2500 & 3000 wet paper to remove some defects that would not buff out with coarse pad and heavy liquid abrasives with great success.
Can the same process ( wet sanding ) be done on single stage ? I am guessing that it can, but need to be careful not to go thru to the primer. I take it that if I went to far on the base /clear, I would see color on the pad and or paper/water, but that will always be the case with single stage-- Y/N ? ( always having color since the base & clear are mixed together when sprayed.

Yes. The only determining factor is film build or paint thickness.

Yes. If you wet sand single stage paint you will see the color of the paint in the sanding slurry. If you buff single stage you will see the color of the paint on your buffing pads.

I guess it takes more pads to do a single stage paint correction

Not really. You want to swap to a clean, dry pad often no matter the type of paint.

• With clearcoat paints - you will NOT see the paint building up on the pad.
• With single stage paints - you WILL see the paint building up on the pad.

Both types of paints build-up, but because you cannot see the clearcoat build-up on the face of your buffing pad - it can seem like you don't need to swap pads often.

Here's a saying,

More pads are gooder

I usually use 7 or so pads per vehicle, & one just for the hood
