The whole point of Solartex is to have a fabric look. There are other good products on the market if you wanted a gloss finish, so before you start covering you might consider switching. To answer your question though, any kind of fuel proof clear coat will work with Solartex. The paint that is on there is fuel proof and durable, but exhaust oil and the dirt that it attracts will get stuck in the texture of the weave. I can tell you that acetone will dissolve the finish that is on there, so I'm guessing that it's an acetone based lacquer or a chemical resistant enamel. Luterkote will work just fine to seal the fabric and take it from a flat to a satin finish, adding some gloss and making cleanup easier. A 2 part urethane clear will work also, as will any 2 part epoxy paint. But if you really want a glossy finish, you're going to wind up considerably heavier and with a lot more money invested than if you had just gone with Ultracote or Monokote. If you want a glossy painted finish, go with natural Solartex (it doesn't have any finish on it) or a glue on fabric like Sig Koverall.
