hi guys, does anyone have any experience of using a GOOD heatproof engine
paint?

How hot ? Blocks? Warm parts with radiant heating ? Exhaust
manifolds?

Most obviously suitable modern paints are capable of being used
successfully on engine blocks. White or pale paints will discolour, but
the resins are heat-proof to this level. Always give them _plenty_ of
time to cure properly before expecting them to be oil or fuel proof.

Good engine block paints are Blackfriars QD90 (has an associated primer
and comes in a range of colours), PPG or Japlac. For hotter things use
Sperex heat-resistant. They even do one for exhausts and manifolds, but
I've never had that much luck when it's really hot. Try a decent motor
factor like Edmunds Walker.

Hammerite is of course useless. It's never much good, but it's
absolutely dire for fuel resistance.
