Epoxy out of recoat window
Guys I have a question about epoxy recoat window. I had sprayed my mustang parts with 2 coats unreduced epoxy and blocked it then applied 2 more coats of unreduced epoxy. Can I wet sand it with 600 grit and shot 2 coats of 25% reduced epoxy and move to base coat?

No. You would need to sand the epoxy just applied. Like I said in the post above epoxy is solvent resistant when cured. So when you sand with 180 and reapply epoxy you are back in the "window" and can apply coatings over it and be ensured you have maximum adhesion. If you 180 then apply 2 more coats of epoxy you need to sand that to flatten and remove texture etc. Just like any other coating. 400 wet for a solid and 600 wet for a metallic are what I normally finish with. You have about 14 days from when you apply the epoxy to when you need to seal it and paint in order to ensure max adhesion.
The 2K urethane mentioned was offered as an option for someone who couldn't do everything in the window. Read that post again. It should become clear. Read the Tech Manual section covering epoxy also. It should become clear. Keep asking questions if you have them.
Thank you!
I’m just a beginner
Chris, so you prefer to do everything in epoxy and avoid 2k?
On a side note this is another project I’m working on (62 vette ) that I have in final prime. On that car I did the body work, then gel coat, then slick sand and then 2 k primed. I just learned about the spi epoxy and was hoping to save a couple of different layers of product .

How about some pictures of this '58 Corvette?
I did look in the Restorations section but didn't see it.

I’m working on my 62 right now . But planning my course of attack for the 58. I have most of the mechanicals done on the 58.
It is a restomod with a 427” ls3 /4l80e with a custom twin turbo system fabricated by a race shop. It sits on a Sriii frame. I lowered the floor 5” and stretched the firewall 3 “

Ken do you use epoxy after your filler work and then use polyester primer and the 2k high build and then epoxy sealer ?

I've done many combination of many paints including SPI epoxy, turbo, 2k high build, clausen rust defender, clausen sandy, slicksand, featherfill, evercoat superbuild 4.1, USC eliminator and one of the Duratec primers. I'm doing the body work on a 58 and 61 now and intend to start with Clausen Sandy over the fiberglass (and filler) and will sand that through to 600, then use SPI epoxy as a sealer, then basecoat.
Here is the 58
And here is the recently completed 63 https://sricemedia.smugmug.com/Automotive-/Paint-Protection-Dallas-2025/63-Corvette-Restomod-11325
