final block sanding...I hope

[red70fastback]

I've got the last of 4 coats of 2K high build primer down and beginning to final block sand. Expecting that this will be the last coat of high build, what grit do I or should I stop at? How much texture will the primer sealer require for adhesion?

I've gone from 320 to 400 on about 30% of the car. Primer sealer is planned to be the PPG Chromatic DLV80 series.

Thanks, Larry

Refer to the fact sheet on your sealer to see what grit it calls for. I'm guessing 500-600

Great, thanks. I'd hate to have to go all the way to 1000

Just asked George, (Shag's painter) and he said 600.

that'll do for me. Still better than having to step it up to 1000. should be there sometime next week

If I wanted to be perfect I might go down to 1000 but 600 would be fine
