Crazing.

Thanks Chad, the epoxy was mixed as normal epoxy, NOT for sealer, for a white finish and a final blocking. Yes I found out that the MotoBase covers incredible after the fact. I was sure it end up being the nut behind the gun.

It's just rushing product, that's probably the only issue, and if you mixed at 1:1 and did 3 coats and tried to paint the next day. That is where the issue comes from, that is to quick to topcoat over the epoxy. This is a situation where I would wait 3 weeks. Is that excessive? probably, however it's safer. I would rather wait 3 weeks that wrestle it for 3 weeks. At least if I wait I can work on something else while it is curing. lol. Keep in mind if I use 3 coats i'm using it as a filling primer at that point, typically in replacement of a 2k primer.. For what you were doing a 2k primer would have been more efficient.

I also find ZERO purpose in applying 3 coats of anything unless the plan is to sand the majority off. My theory is that if you are putting 3 coats of something on you should sand the majority back off, if you are not sanding it off, what have you achieved? 3 coats is a fair amount of millage and when blocking that off you can fix imperfections, and also level out the surface, if you left three coats on you are just increasing the mill thickness. And I always feel thinner is better.

Agree. I did sand a lot of it off as the final blocking as this was going to be my final blocking . I could see I was getting close to the grey 2k underneath in a few places.... But there were places it was still thick, likely my trouble areas.

When we sand our primer we always sand until we see the underlying color. mostly because I don't like to much build. And that's the idea, the low spots stay a little thicker while your high spots get really thin. That's what gets everything extra straight. Aside from the issues that car does look great. I need to find some motivation to get back to my projects.

Chad, On waiting three weeks, would you not want to sand the epoxy within a couple days? Isn't it really hard to sand after an extended cure time?
