This surfacing agent or "wax" is a 10% paraffin solution, so it requires less liquid(dilution) to make it do its job. It rises to the top of your gelcoat film, sealing it from the atmosphere, giving it a tack-free finish. When added to gelcoat that we ship to you, expect 1 oz quantity sized for a Quart, 4 oz quantity sized for a Gallon. Read the mix chart for more product information.
