Primer HELP.

[simmy]

I use 2 pack paint through a spray gun to paint alloy wheels. The primer i use is from aerosol cans namely upol etch primer or the high build primer. Are these aerosol primers compatible with the 2k paint?

Also is it advisable to only use 2k primer when painting with 2k paint?

Would spraying 2k primer using a sparay gun provide better adhesion than using aersol cans?

Thanks

2 k acid etch is nice on bare aluminium then u can use high build primer . then 2k topcoat or as seems to have taken over epoxy primer , 2 k can be sprayed over most paints celly ect with no adverse efects . spray guns better than out of a aerosol can

will using epoxy primer provide better adhesion?

About the same, but it's a good sealer. E.g. 3 months or so ago I made wing quarter panels and other bits, welded on & coated in epoxy only. Been driving every day and no rust. (will get full respray soon)

ive allways used 2k etch then high build primer its excelent stuff on aluminium. maybe when i run out or cant buy it cheap il try epoxy

Epoxy sticks better to ally better than even etch.

At the moment i only use etch primer and then high build when the wheel is stripped down to bare metal.

If not stripped down to bare metal then i only use the high build primer.

I might give the epoxy a try. On bare metal would i use the expoxy and then the high build?

it sticks no better than 2k etch but can be left longer before a topcoat is aplied as is less porous

thinking!! has langy shares in epoxy paint??

Ha ha ha, Obviously i used etch before Epoxy came along, I would never use etch again, The epoxy is such a far superior product despite what Brightspark says, in my opinion of course.
