Common Questions
How Fast Do Orders Ship?
Orders placed by 3 PM ET on a business day ship the next business day. Enter your ZIP on any product page to see your delivery date before you check out.
Can I Buy Fiberglass by the Yard?
Yes. Cloth, 1708, mat and carbon fiber are cut to order from full-width rolls, from 1 yard up to a full roll. The price per yard drops on longer cuts.
Polyester, Vinyl Ester or Epoxy: Which Resin Do I Need?
Polyester is the standard for boat layup with mat and 1708. Vinyl ester adds water and blister resistance. Epoxy bonds best to old laminate, wood and carbon fiber. See epoxy vs polyester vs vinyl ester for the full comparison.
How Much Resin Do I Need?
Use the resin calculator. Pick your fabric and area and it shows how much to order.
