You are buying one gallon of Premium Polyester resin. including MEKP hardener, and Surfacing wax. 
Color: clear- amber


All of our Polyester Resin is sold WITH MEKP HARDENER INCLUDED IN THE PRICE , we give you more than you will need.. MEKP IS included in the purchase price !
We also give you WAX , so you can use the resin as a waxed resin of you choose.

For a resin of this Quality this is the best price  for a gallon of resin that includes hardener.

Freshness is so important when buying polyester resin.
Because of our low price we sell a lot of polyester resin,  and get in new stock about every two weeks.
People who use our resin rave about it , and never  buy any other brand again !

Polyester laminating Resins are the most commonly used resins in the marine industry. These resins are MARINE GRADE   and  hardened with MEKP. When working with these resins it is advisable to wear gloves , eye protection, and a chemical respirator. These resins can be used with all types of fiberglass cloth and mat. Polyester resin can be used with carbon fiber, urethane foam, and core materials, but not Styrofoam. Polyester resin is rigid when cured.

All of our resins are sold WITH WAX ( and MEKP hardener) in separate two ounce containers. Wax and MEKP are included in the purchase price !

When polyester resin is used without wax, it dries with a tacky surface that allows you to add a second coat without sanding. If you add wax it dries to a smooth , slick , not sticky , non tacky hard surface.. (This thin wax layer must be sanded away before painting or adding another layer of polyester.) The advantage getting wax with your resin lets you decide whether to use the polyester without wax so multiple layers can be done without sanding, and then add wax to the polyester resin before the final coat. No need to buy two different kinds of polyester resin when you buy from us !

MEKP drying agent, and wax mixing directions come with the resin.

We sell Gallons, five gallon drums .


polyester resin is the most versatile resin you can buy. Do you think the resin at the home store or the automotive store is fresh? .. We receive shipments of resin at least twice a month, and we keep the MEKP hardener refrigerated until shipping!.

    My opinion

    Posted by Jim Lavely on 2nd Jul 2018

    I'm a novice at Fiber Glassing. I used an other brand & found it OK. But than I discovered FabergassSite while looking for a resin without the wax added. I decided to try their resin. So far I have been very pleased Also the price is very reasonable. I like that it comes with the wax separate so you don't have to sand between coats & than add it for the final layer I also purchased their Gel Coat for the same reason, the wax is separate. I'm hoping the experience with the Gel Coat will be as good as it was with the resin. The shipping was also quick, but a little high The 20% off shipping really helped

    Great stuff

    I like this product for laminating glass. It has no wax in it so it remains tacky when dry. Therefore, you don't need to sand between applications. When you are ready for your final layer, simply add the wax in and it dries nice and clean.

    fiberglass anything

    Posted by Glen Patana on 28th Aug 2017

    This is my first time fiberglassing anything. It worked like a champ, but quite messy. I fiberglassed my outdoor sauna floor. No leaks works great the gelcoat was a nice finish to the floor. The instructions were easy to follow Thank you!
