RE: Source for Solartex
As far as I know, thats it.
If you haven't used it before, you WILL LOVE IT. It is noticably lighter in weight than Coverite fabric (yet just as strong ), does not require the frame to be coated with BalsaRite first (SolarTex adhesive is excellent) and does not require any overlaps to be coated to insure they will stay attached.
One thing I would suggest though. SolarTex has a more open weave. Because of this I would suggest giving the finished product a clear coat of a water base polurethane to seal the weave and make clean up easier.
