Hello everyone. In a previous post i had issues with some big sky epoxy over lacquer paint. I resolved that problem with nasons epoxy. I put on the epoxy this morning followed by two coats of 2k primer. I blocked that this evening with 400 grit. My plans are to paint the firewall then put the cab back on the frame. I noticed while blocking i was thin in places. My question is can i come back later with a couple more coats of 2k over this 400 blocked 2k. Thanks....Sam
