That is tosh. I painted a gate with a metal zinc stuff, and used Hammerite
over that and its been on for 20 years and is only now chipping due to some
rust underneath.

Can you protect the Hammerite by masking? It is only the bare brass you
need to clear coat.

Or clear coat everything first, let dry completely, then add the
Hammerite.

It's probably the "faster" solvents in the clearcoat that attack the
Hammerite,
and those will dry off.

Not thought of that .... as long as Hammerite will paint smoothly on top
of it and not run off - it is a heavy paint.
Went to web site it states do not apply primers first, but once I clean
back off may try this.
