Contacted pond coat company, he said,
"
Thank you for your interest in Pond Coat. Due to the elongation properties of our product (850%) I do not feel it will add any rigidity. Yes you can use fiberglass mats under our product and it adheres very well to most sub straights such as wood, metal, fiberglass with out any pretreatment except pressure treated wood or galvanized metal. Prices are as follows:
gallons- $55.00
5 gallons- $231.00
55 gallon- $1,700.00
Please feel free to contact me with any questions you might have.
Respectfully,
