To cover wood a laminate using epoxy resin and 10 oz cloth will yield a much better job than 10 oz. Vinylester is essentially a styrene modified epoxy resin.

Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance. Because of their chemical structure vinyl esters and epoxies offer higher mechanical strength adhesion and heat resistance over polyester resins. Standard epoxy vinyl ester resins are limited to 220 250 o f 104 121 o c in most applications. Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid.
