I had problems with my finish as well. Had to sand back some areas. It was an irritating detour that stretched a few weeks and really slowed the build process. But in the end I learned a few things, got the problem got sorted and I'm back on track.

It'll be the same for you. I've been watching your thread. Your build is gonna look amazing. And in the end the marine blue looks like it'll be great.

Just wanted to send some positive vibes your way!
