Ins't Blue River a water based system?

Blue River doesn't make aircraft finishes anymore. It was a
terrible product. My uncle used it on a Champ, and the airplane ended
up way overweight and the fabric would stretch and sag on cool, damp
days. Apparently this was all too common.
And I am, at the moment, recovering a Citabria that had the Blue
River stuff on it. The finish was cracking and peeling something
awful, the tapes were lifting, and the airplane was overweight. The
fabric and finish were only ten years old. There's no way at all I
would ever use any water-based system until I've seen it work very
well on other people's airplanes and survive the weather for some
time. I've seen and heard of too many wasted cover jobs.
Stits is now known as Poly-Fiber. It's also owned by the same
people who own Randolph. Go to http://www.conaircraft.com/

I bumped into Ray Stits a couple weeks ago, and spent about 15 minutes
talking with him before I figured out who he was.

He appears to still be involved with aircraft covering systems and
supporting products.
