Re: 1969 Lonestar Medallion
May have needed a better wipe down to get all the dust off... Or more aggressive sanding to give previous coat more tooth for the current coat to grab... It doesn't penetrate the previous coat like it would raw wood, so it often behaves much differently.....
good mixing of the resin pre & post catalyst? And does the epoxy your using have a 'dwell' time before you use it?
different heat & humidity levels don't really change ratios on epoxy like it does poly resin & MEKP, does it?
sorry, long day is catching up w/ me, I hope that ^^^ helps, have a great week
