FastCoat

Kraken Bond
Evidence score86.7/100

The only kit whose one dated, revision-numbered sheet carries both halves of the claim: the 20 board feet per can with the conditions behind it, and the surface-burning result, both indices at a stated thickness.

FullStop

BEEST
Evidence score58.5/100

The largest Amazon buying signal among the kits we track and the thinnest paperwork of anything ranked: no technical data sheet at all, and 25 of the 225 reviews on its own store carry the verified-purchase label. What it does publish sits on a page its own listing never links.
