Thanks, Todd. I'll call the store tomorrow to see what
their story is on this stuff.

Finally picked up some Pre-cat lacquer to expand my
horizons. First attempt demonstrates it needs to be
thinned. From the sources I've found in books, I'm under
the impression that it's treated like regular nitro as far
as thinning goes. Is that correct? Today I sprayed it at
80 degrees, high humidity (unusual for northern Cal) with
HVLP. I couldn't get flow out without putting on so much
the result is that dreaded "plastic" look.

I've e-mailed the mfg. for viscosity cup timings but in the
meantime (and WITHOUT A cup) I'm looking for GENERAL
guidelines as to thinning ratios. 10-20%?

What's about the max you can thin this stuff? Ratio for
first 2 coats and ratio for topcoat? I'm thinking I should
go with thinning before I consider a retarder; correct?

Pre-cat laquer definitely has a shelf life, and it's a lot less than
shellac. When I bought the Sherwin Williams flavor of precat, they put a 6
month use-by date on the can. I have no idea what the results would be of
using a batch of precat after the catalyst has "worn off" so to speak.
