Yep, I'll admit I didn't do a search, so if this has been addressed, apologies all around.

I have a couple of questions:

1. I have sprayed my car with Nason Selectprime, and I have noticed a couple of small valleys. Can I use Sikkens Kombi putti over the primer, sand it down, and be good to go with the single stage Nason Fulthane I'm planning to shoot?

2. After spraying the Selectprime, I felt that 400 grit was not enough to knock down the mountains of orange peel. I sanded with 320. Do I need to follow up with a finer grit before I spray the Nason Fulthane, or will the 320 grit be ok?

Thanks in advance for any help. Again I'm sort of a newb at this. I don't need to be sold on BC/CC. I'm doing single stage for good reason.

1. I'm going to say tread carefully, maybe call Sikkens tech line to be sure. Their number is in the tech sheet for that putty.

2. 320 grit should be fine, for SS - assuming you are doing more than a single thin coat.

It's a good idea to always prime over any putties before paint.
It doesn't take much, just enough to cover it and seal it against the paint.
Most putties absorb solvents, and swell a little.
