I heard you say that you use OHW as a primer for other paints in your shop. I tried this today and the OHW just melted off. I have a welding hood that is (was) a dark navy blue. I was going to paint it with a synergy green from Low Country Hydro Paints. I wanted to brighten up the base color first with some OHW white so the finished product would be as vibrant as possible. The OHW white went on as per usual. Two light coats. About 10 minutes between coats. I then waited about 20 minutes and started with the Low Country synergy green that we had in the cabinet. I have used it on speed shapes before and it did perfectly. What happened here? Not enough time between the OHW and the green? Incompatible paints?
