[Healeys] Powder Coating Springs

[Charlie Frazer]

Kees,
I respect your expertise.
Could you tell me the specific evidence on which your caution about

What specific effects are there on springs and roll-bars heated at 400
degrees?
Thanks,
Charlie

These relatively low temperatures of 400 do effect some some types of spring
steel of springs, anti-roll bars etc. so beware. There are little effects on
