Bit confused about what to prime with.
in past used to use dupont 215S Zinc Chromate.
I have used dupont Variprime self etching primer under Imron with good results.
Just talked to Paint vendor, and he warned that variprime is not a good stand
alone primer. Said that the Phosphoric acid that does not
react with the metal being primed reacts with the Zinc Chromate to neutralize
the acid. said because of this it is not as good as the old
215S but an excellant base for top coating.
His reccomondation was #2580CR. It is a DTM (Direct to metal) epoxy primer that
is much more user friendly as compared to Corlar.
It has Zinc Chromate in it and is an excellant stand alone corrosion primer.
Thicker than variprime, and would probably brush on much
better. Works well with steel or aluminum.
Anyone have any experiance with 2580CR?
Other comments?
