Rich,

Do you have data for anyone else using Acrylic Enamel top coats and
failing. There is got to be some chemistry here. Humidity? Lets see...
"the famous" failure case I know was in the humid east coast place. Is
the humidity a factor? In SD here humidity is low - especially in a
heated winter garage.

I applied UVSP on my composite in 2003 and toped it with PPG Acrylic
Urethane. No problem so far. My guess is that the combo of UVSP with
the same company Top Gloss had problems.

There are many reports of UVSP having problems under other top coats
as well. I personally know of failures (bubbles filled with ooze)
under Sterling LP, Imron and Chromasystems topcoats. It looks to be
about a 15-25% failure rate.
