Gotta question here, I’ve used Polyester surfacer in the past (1993) and had problems with checking and crazing (evercoat brand ). so since then i stopped using it and stayed with urethane primer surfacer. what do you guys use or prefer for primer surfacer? any economical brands? polyester or urethane?
i do poly on anything that i absoulutly dont want to shrink especially resto work the new polys have came along ways since 93 an yes im using the ever coat brand they got a new one thats called 4 ta 1 thats really nice funney that thats the mix ratio to keeps ya from over or under indexing it which can cause ya greif try it youll be suprized 😉
i love polyester, i dont base directly on it though. i use it where you would use a glaze or need a light filling. i cut it with some 150 then urethane primer over it.
i use it on all my restoration work, cant beat the build that stuff has. after i block that down i come back with some k36, seal then base and clear
I usually only use it on resto work too. Big body repairs I’ll sometimes use it too, almost always top it with a urethane primer, lower end stuff I’ll use a urethane wet on wet sealer instead.
