Hi Norman,
I checked out your site- you guys are really creative. I think that our Styroplast will be the best choice for TTT's. It is super tough, light, waterproof, weather resistant, and is easily brushable so no spray equipment is required. Although you can use a mesh (which we also carry) to make it super strong, it is nearly as strong as resin and fiberglass all on its own, it's stronger than epoxy. You have to paint or at least primer it right away to get the best paint bond. Otherwise you have to use an expensive epoxy primer on it after it dries. It is used for coating props and backdrops in amusement parks where it's got to hold up to lots of abuse. Truly an amazing encapsulant.
Here's a link to a bunch more information on Styroplast:

If you or another active member wants to do a review we can send you samples at discount prices.
How are you guys cutting the foam now?
Best regards,
Dave
The problem with the Styroplast is it is a bit pricey, but then again, it may
be in the same ballpark as an epoxy coating? I don't know as I haven't done
a comparison of the two. If someone has experience with epoxy coating
costs, then please chime in on this. The Styroplast is $85 per gallon. The
above link from HWFF has the coverage info.
Here's a corresponding link for their Foam Coat product:

This is much cheaper - @$29.95 per 25# box, and would probably need
their "Boost" fortifier additive @ $27.94 per 32oz or the "Bounce"
rubberizer additive @ $19.95 per 32oz depending if you want a real hard
top coating or one that's flexible.
The final cost determination would be how thick one wants the final
coating to be. Since these coatings are either a light tan or light grey
they'd need to be painted anyway so that'd probably take care of any UV
concerns.
Just wanted to pass this along. It'll be interesting to see Mel's test strip
results once he gets them done.
The reason I've been pursuing this is I was wondering if these coatings
would be longer lasting or more durable than the TBII&III glues and
paints as it has been mentioned that those are sometimes thermally
affected. And then there's the bedliner type materials as well to think
about in this area too. Costs and weights also enter into the picture when
trying to decide the best choice here as well. So just gather all the info
we can, evaluate for your situation, make your choice, and go on from
there, would seem to be the path to pursue.
Cheers,
