On my 74 Charger I have painted the bottom, engine bay, all four wheel wells, interior, and trunk area. All these places I have media blasted, cleaned with wax and grease remover, primed and top coated with no problem. I painted the front and rear valances the other day and it orange peeled. I am using PPG DP50LF epoxy primer with DP402LF catalyst. PPG Deltron 2000 DBC paint with DT 885 reducer. Devilbiss primer gun 1.5, paint gun 1.3 at 30psi.
Three things different: the valances were sanded starting at 120 ending at 600 wet, the temp in the shop for the valances was 85, for everything else they were painted at a temp of 73-75 using a heater. The humidity was around 45-50% for the valances and around 10% for everything else. I used the 885 reducer for the valances and 870 reducer for everything else.
I wiped it down with wax and grease remover many times until it was clean.
The primer orange peeled and I guess the paint followed. Not sure what I did wrong or how to fix it. Thanks
