I have repainted my PA28-140 twice in the last twenty years. The only
paint I would recommend is Dupont Imron. I have tried other paints on
the trim areas but they did not last. Imron is very toxic and must be
used outside or with a respirator if in hanger. Zinc chromate is bad
for your health also, so be careful.

If you use Imron just use a splash of accelerator otherwise it will not
gloss well.
