What grit after re prime?

[slow93z]

The black epoxy sprayed as a sealer would be easier to cover with a dark grey metallic. Meaning it would take less coats of paint to cover, I'd say if your epoxy is compatible with the paint brand your spraying then just use that as your sealer. No need to spend money just to get grey. What brand paint are you spraying?

The most available brand to me is ppg. I'll be using the good stuff. Deltron "dbc" i think it is. Correct me if I'm wrong. I will not be using the lower line Omni

Avoid using a wet on wet sealer approach with fine metallic base coats. Yes guys do it and some guys have the right gun and thin the sealer just right, but I don't recommend wet on wet application. If you must spray a sealer, then plan to wet sand it with 500-600 grit minimum for fine metallic base coat.

Otherwise you will see an ever so subtle texture "grain" under your clear coat as the sealer will leave a small orange peel and the fine metallics will orientate around the highs and lows and reflect the light differently.

Also, if you are planning to go metallic base or tri-stage, consider having an experience painter by your side to teach the proper technique. You really need to fan out your spray pattern and dial your settings just right.

I will respectfully disagree with previous comment about sealer

Can you share the reducer amount, gun settings, and specs you use to spray the sealer? It is not for the inexperienced if you want a top quality job.

I got the car re primed today with spi regular build surfacer. I plan to block with 320 first then go from there. Hopefully the blocking will go faster this round as it should be substantially straighter than the first time knocking it down with 180

320 block is done. I'm glad I did it. I feel like it added an extra level of refinement to re prime it and hit it with 320. I still had some break throughs but not near as much.

I'm about half way done wet sanding with 600. It's going quite fast as I really spent a lot of time doing a thorough job with 320

Buy some 3m powder guide coat,rub it on and wetsand 600.
This will give you the best results.

Btw,i think you need to prime and block a couple more times before wetsanding.
Your still new to bodywork,and even thou you
Feel its straight,its better to block and prime a couple more times before wetsanding.
You stated its going to be show,so i would keep sanding.
I know most dont like hearing that,but its the hard truth!
Thats why its called body work ;)
