I just started following some of his stuff on here several weeks ago and I couldn’t tell you. He’s always building up something and while most of us avoid epoxy except for maybe sealing he’s not afraid one bit of using it. I did buy some sealer he likes
devcon is no joke. i've used it to seal up the wells in Q-jets and repair TQ bodies. glove up and tape/paper off the work area. anything that stuff cures on it's gonna be there a LONG time.
