No Dan they are not fiberglass, some kind of poly that has been roto molded I think? most like other ultralight tanks? I will investigate the Pro-seal to see the specs?. as you guys have used it successfully I have no doubts?. I will attempt to obtain the specs on the tanks and then return? Thanks of the response all of you? jw
