RCU Forums - applying koverall with WBPU

I've been experimenting with fabric, latex and polyurethane coatings for a few years, and really like the ideas in this thread.

Will definitely have to try the dress lining on my next project (Giant Telemaster), should save a few $$ over Koverall. Had the idea to get the dress lining in the basic colors I need, then could literally use it as a trim color fabric after coating with WBPU. Should be light & plenty tough. Thanks for sharing the technique, Sscherin!

I've been getting stuck on clear-coats, though. I fly glow, and in my experience water-based polyurethanes (Sherwin Williams exterior Spar urethane) do not hold up to glow fuel. Have heard solvent-based PU does but has an amber tint. Then there is Klass-Kote (solvent based epoxy) and Nelsons (moving back to Chicago, hope he remains a going concern). In the end I have settled for rattle cans of gloss or satin Lustrekote, though one needs to take care and apply light dusting coats over latex. My goal is to get "solvent-free".

Sscherin, could you recommend that brand of water-based exterior PU that holds up to glow fuel? Edit - Found what you used (Valspar water-based spar urethane) but having a heck of time locating it! May just experiment with the spar urethanes I can find.

And I see that Nelson's paint is cross-linked polyurethane. Can one just use their crosslinker in off-the-shelf WBPU? Or get the crosslinker elsewhere?
