Final Sand Before BC

[Machspeed]

I know this is a topic beat to death here but I'm still left with questions after searching and I need to purchase paper. Question is: What final grit to sand 2k with before application of basecoat? Basecoat is metallic. Caveat here is, car will be sealed with SPI epoxy 1:1:1.

Thanks!

320 with sealer, 800 without sealer is what I do.

600 grit is the standard.

I like the 600 grit before sealer because it lets me see what the base coat is going to look like.

I use what Barry suggested, 600 for metallic and 400 for non metallic.
