I have attempted to use Aqua Gloss on several projects with less than stellar results.
I have, in a previous post likend it to wet snot, appologies for the rather untasteful analogy.
I don't have access to Future, so, I will continue to use Testors Gloss or Dullcoat untill a suitable alternative makes it self evident.
I have been meaning to try out Tamiya's X-22, from others experiences with the product it meant to be bullet proof when correctly applied and cured.
Good luck.
