PACER Z-Poxy finishing resin for fibreglass fuel tanks
Hi All,
I don't post here often, and perhaps this should be in the composites thread instead, but all the jet guys are here and I'm building a jet!
I am making up some fiberglass fuel tanks and was wondering if anyone has experience with Z-poxy finishing resin as a resin system for this application? The spec sheets says it's solvent resistant, but does anyone have any actual in-service experience with this stuff - will it withstand kerosene and diesel fuels over time?
The resin doesn't seem to cure as 'crisp' as others and I'm guessing this is because it's a little softer to make it easier to sand since it's a finishing resin... it does however make the laminate a bit more flexible which is a good thing for a fuel tank, not so?
Any input appreciated, thanks.

I've made multiple small molds and parts using Z-Poxy Finishing resin and routinely use it to fuel proof firewalls and such but I've not used it to make a fuel tank. My guess is that it would work just fine. Be advised that it may become brittle over time. Adding a small amount of 90% rubbing alcohol or denatured alcohol (maybe 10%) can minimize the brittleness though.

Z-Poxy is what I would always use to do the final seal on Kevlar tanks . That was even after it may have passed the underwater pressurized test . Just got a warm , fuzzy feeling by doing it .
