What primer to use

[Alex van de Wetering]

Jason,

I am using Rustoleum 769 rusty metal primer (comes in grey and red/brown) on my Chev and I am happy with the results so far. It's 1K, can be sprayed or brushed and fills grooves nicely. There is also a related primer in spraycan 2269....this has slightly different ingredients, but I use it for touch-ups and to spray bolts after tightening them.
769 is a rust primer, so bonds to light rust, which means its ideal for my way of restoring....I clean a lot of parts with a wire brush on the angle grinder...even though I continue until the part is completely shiny, it will still leave small rust parts, even though they can't be seen. The 769 bonds to this.

I used a PU primer previously, but wasn't impressed as rust was already showing a year after I cleaned, primered and painted parts (OK, they were left outside). I am guessing the PU WILL work when you sand blast all your parts.

A lot of guys in the UK use Bond-a-primer, which seems to give great results as well.

I remember when I was looking for a new primer, that everyone uses a different brand making it hard to choose which one to buy!

by the way....red oxide containing lead is still available here at specialist suppliers. It has been banned for years, just like in the rest of the world, but it seems it has become available again as for some applications there just is no alternative, or the alternative is just as toxic (?).
