As a newbie to HVLP, I have encountered the following problem...
I am spraying Minwax (water-based) Polycrylic semi-gloss
polyurethane.

FYI, polycrylic is not polyurethane. It is acrylic and urethane is
*MUCH* harder and therefore scratch resistant.

Don't assume that harder means more scratch resistant.

Scratch resistance is one of the defining characteristics of hardness.

Not to get all 'clarke' about this, but tire rubber is, in terms of
hardness. very soft but very scratch resistant.

You succeeded, though. :-)

HEY!........ouch!


Happy Thanksgiving! :-p
