Even if there was 3 each side, one at each end and one in the middle, or even 2 each side, one at each end, that would be enough.

water ?
But the idea with epoxy is that it finds it's own level then hardens to that level and job done, with the method you suggest how would you measure the depth of clear coat (water) to know that the frame underneath was level ?

What i suggest isn’t so different with the epoxy method. Clear coat is also a resign but I think much more cheaper that will harden when it cures. Water isnt hard unless it becomes ice. Water could give us a perfect level but the question is how we could “capture” that level. What about self levelling floor resigns ?

ba99297, Sorry, it sounds like I did not understand what you meant with the clear coat, I did not think there was enough strength in clear coat when it hardened.

Oh I'm sure I'd read somewhere you had a Leak.??. . but obviously not so I stand corrected you obviously don't know.!! . . .But I assure you that you would run around trying to stop a leak if it happened no matter how COOL . . :hysterical:. . . you think you are.!!

The problem comes from the type of resin.? I think Car paints and self leveing Floor paints which are manily polyester resins contain high solvent levels which evaporate and can cause sinking etc.

They wont shrink or sink but they do not harden to the same levels as paints are meant to be somewhat flexible to resist cracking etc, so it wouldn't be suitable for this particular job as it would 'give' unlike the epoxy resins used in these forums before which cure fully.

Should I remove these then? Im all for saving material, especially considering the prices of steel these days!

I belive it does shrink and it's why Only Solvent free Epoxy resin is used for Epoxy Granite to avoid voids, sinking and cracks appearing when solvent evaporates.!!
Regards the steel and bracing then yes you could reduce quite a bit of that steel.
