Primer ?

[pxr5]

I have used in the past a brushable red oxide primer & it was high build, easy to sand down. Ive since purchased a can but its not as good, any recommendations? thanks

The best primer for car bodies is 2k epoxy primer because it's non porous. It dries to a slightly shiny finish. I've used various 1k primers from cans and even the good ones like BH Electrox which is high zinc are porous and will rust if left outside. More recently I've used HB Body primer, brushed on, in the non visible parts of my car resto.

Unlike most 2k paint epoxy primers don't normally contain isocyanates so are safe to spray at home. You can roller or brush them on. Over on the mig welding forum Jotun epoxy is highly rated for under cars and Lechler 29107 for car panels.

If you don't want to mix 2k, Bilt Hamber make decent ready to use primers, aerosol and tinned, though they are pretty expensive.

Use an epoxy primer as said above. Adheres to most surfaces including bare metal, is waterproof and doesn’t contain iso-cyanates. I use Lechler, brush it on or spray it.

I’ve used Octoral EP130 epoxy primer on both my Cortina and Escort. I find it’s brilliant stuff. Like all epoxies it likes a thick coat. My Escort has been in primer for over a year now with no rust coming through after media blasting.
