    Im going to VE layup the rest and let it set, then heat up with propane heater that night for 5 hrs. Or maybe the next day. Within 24 hrs. Then, as long as it has fairly cured, i will water/ degreaser/ hot water wash and then acetone wipe and then also wet the tank with a sprayer where im then applying the 2000e. I will apply greater than an ounce per square foot of 2000e.

    If there are bubbles down deep, which there are, because the VE and 2000e are acid resistant, and also will barely pass water, the bubbles acid osmosis won't and cant affect the layup.

    Right?

    Heat won't cure it. Time will eventually do it, but I doubt you want to wait at least a year. Just go back to the place you bought the resin from and buy a small bottle of wax additive, it's cheap.

    Seeing your pictures, my advice is to return the VE resin and the 2000e (or put them on Craigslist) and use the money to buy a gallon of epoxy and some plain woven fabric, then go over the whole tank with it until you used it all up. Raka, Inc. 772-489-4070, Epoxy-Fiberglass-Carbon-Kevlar http://www.raka.com/ is up your alley and cheap.

    The VE and 2000 are incompatible if the VE isn't fully cured.

    You are mixing and matching stuff that isn't helping you in any way, this is complicating everything you're trying to do.

    Since you only have two layers of half of something, use the VE and add another layer with no defects, put a layer of waxed VE over that and you're done.

    Skip the 2000 completely, it's of no value in this build.

    As mentioned, you could put epoxy and glass over it too, but you already have the VE.

    Thanks for finally posting pictures.
    I now fully understand your fear of leaks, the interior structural parts and pipes almost guarantee that, on top of a questionable laminate schedule and lamination quality.
    How about a tank liner, or a drum fitted into the space instead?

    Finished it. 5 hours 125-170f throughout tank, with heat gun and metal bowls. And laser temperature thingie.

    The VE was gnarly. The 2000e nearly melted my eyeballs.

    Thanks everyone

    By the way, it showers really good, no curtain at all!
    --- note the 'bondo with glass' making up a nice drain in the corner there!
    The VE is insane compared to the PE. VE sticks so hard its crazy, and its super stiff and strong. I have some on the outside of a cracked plastic motorcycle gas cap ... It still sticks!

    This method of painting over the poly worked fine, but just because i cured it for so long and so hot. Before that it was sticky, but once cured you can tell,because it scratchy with your fingernails.

    I also razor attacked and hammered every spot on the tank. It needs to sound like a tank!

    So far , so good!

    Oh yeah lol propane heater was BAD IDEA lol i burned a spot on the bottom of the lid! I just chopped it out and redid it though.


    ALSO you gotta know ... I was lucky i began the glass on the bottom of my tank lid/shower floor because the 1st layer glass drying initially WARPED the 3/4 plywood! So its still good now, because its warped to drain water BETTER but could have been worse if i had begun on the top.

    NO i dont recommend this task to a FRIEND ! lol

    The bendy thing is a tank rinser. It has holes in it. Its PEX. Its sealed in with through hull sealant or whatever its called .... The below water level silicone like stuff.

    I made the drain into the 3 inch with about 3 layers of matte and VE. Its strong as hell. It wasnt too hard. Just be sure to let it melt the matte first, and then its easy to manage.

    I told u guys id reinvent the shiiter. And well, what do u know,?

    Shitteir reinvented.
