Should I move to 2k?

[dhutton01]

Does sealing the old epoxy make it allowable to spray 2k and/or base over the old expoxy?

Or would the order be, (1) coat of unreduced epoxy then a coat of sealer (reduced epoxy), before 2k and/or base?

It’s pretty explicit in recommending sanding old epoxy with 180 before shooting more epoxy. So it’s sort a back up and start again sort of thing. This is why I never leave anything in epoxy long term. I don’t want to back up. So I always shoot some kind of primer over epoxy if it’s going to sit long term. Others may recommend something else but that’s what the tech sheet says.

I like this idea myself. Wish I had recognized this earlier. Seems everyone is all about "get it in epoxy so its protected" which I understand completely...just didnt know it then required a step back to get it moving along again.

For this reason, I think I will spray 2K on the tops of the doors and trunk lid that I put epoxy on last night.
The underside of the trunk and the interior side of the doors were sprayed with epoxy a month or so ago. Im guessing this means I should tape them off, spray 2k on the outside surface, then when Im ready to paint scuff everything, spray sealer on everything, and then spray color.

I was hoping to be able to spray the underside of the components and the inside of the doors at a totally separate time but because I messed up here with the epoxy time frame, it seems everything should probably be sprayed at once. That way I am sealing everything at once and getting color on at once...otherwise I'm afraid I'll run into a time restriction situation again.
