Thread: best primers

Tweet

the way i did many paint jobs was etch primer then a epoxy followed up by a build type like a 2k and i mixed brands at the time .i like duponts and sherwin williams etch primers and used aDP 40or 90 the hi fill primers from ppg or williams and top coated with ppg paint at that time ppg did not have the best etch primer but did use the dps from ppg but they did not lock up like the acid etch primers from dupont or williams to steel did some very basic test panels to back this up with many jobs done this way #1 wash primer/ acid etch #2 the dp 40 gray green dp90 black i like the 40 just seamed to cover better and they made like said more colors. then #3 a hi fill primer i used ppg or i like said williams then i would tint the last 3 coats to color of the top coat and sand up to #600 wet dry i allways like the sanded final primer to be sanded before for the color that is if you what dead flat paint job but did thinned the dp and put just a coat of dp to seal the primer . i was not trying not to go here and how or what i did .just to tell you that the 2ks will not do all the filling and fixing of work then you would be ok with any of the name brands
