Jim, true and similar as to the acrylic in the mix (oxidation?), but
there's still solvent in them all and require thinner, but gov't wants
it out of there. So there's now less of it, but solvent is the
painter's friend, and the hint for potential trouble are words like
low VOCs or high solids. Especially for HVLP guns, as I noted in a
discussion board of auto body people and lurkers for wisdom. It's
like you just can't just buy a DeVilbiss HVLP anymore, but only a
certain model Binks or DeVilbiss with a certain tip will shoot
Brand/Type X, especially clearcoat. Try a higher temp thinner than
OAT calls for, etc.
If a pro does a great job, I think lately it's the shop, and not so
much the product. It may be also that where the shop operates permits
them use traditional guns. There used to be a paint shop in the
hangar near my plane. The mandatory air scrubbing eqiup was enormous,
but nary a whiff when some bizjet was gettin' gussied up.
Reg,
