Product Details

Our West System Epoxy kit contains everything you need to tackle epoxy repairs and fiberglassing projects. Each kit includes a gallon of West System 105 resin (105B, .98 gal), 205B (fast) or 206B (slow) hardener, mixing pumps, 6 ounce fiberglass cloth, mixing sticks, the official West System user manual, and the West Fiberglass Restoration book.

205 fast hardener is used primarily in cooler temps or for a more rapid cure. 206 slow hardener is used in warmer temps or when more work time is needed.

The Gougeon Brothers (founders of WEST) have been producing an effective epoxy for boat building and woodworking for over 35 years. While items may also be purchased separately, purchasing the complete kit saves time and money.

Info & Guides
Both epoxy kits come with the WSY-300 standard plunger pump, but are compatible with the 306-25 and 309 Pumps. The Resin to Hardener ratio for the 105B Kits is 5:1 by either weight or volume. When combined with 105 Resin in a five-part resin to one-part hardener ratio, the cured resin/hardener mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties. These kits are not intended for clear coating.

I great starter kit for those just starting fiberglas repair
By Shane from Edgewater, MD

Verified Purchase

Love the metering pumps. No guess work. I did order with the slow set resin and that was a good thing. Working in 80 to 90 degree temps and resin still set up fast, especially if I had 4 oz or more in the mixing pot. Kept the resin in the fridge overnight to give me a little more working time. Working on a lot of underside locations. In those cases was good that the epoxy got tacky fairly quickly to put on fiberglass mat. Got a good result.

Bottom Line Yes, I would recommend to a friend

West System proves it's reputation
By Denis from Lake of the Ozarks, Missouri

Verified Purchase

I needed to replace a defective stringer in 1973 Mastercraft and heard that the West System was the best product to use in conjunction with the new wood. The product was easy to use and the "kit" came with everything needed. Jamestown Distributors had the best price, delivery was quick and support was excellent.

Bottom Line Yes, I would recommend to a friend

I am a wood worker and use this product to fill open knots, splits, checks, cracks, etc. in rough sawn slabs. The pump dispensers are great! It doesn't get any easier than that.

It works
By Mike from Rabun Gap, Georgia

It works as advertised. Didn't use it to repair a boat, used it to repair gaps and knot holes in the deck, deck table and chairs, hickory hardwood floors where our dog had dug and chewed holes.

No PhD in chemical engineering needed
By Harpoon Harry from Eastern Shore of Maryland

Verified Purchase

I've read about WEST System epoxy since I believe college. Maybe never had the time but I've just retired and for the first time used the WEST system glueing up a dory bottom. Had I used the WEST System when I first read about it, I would have lived a totally differenc life. I've never had a better glue up and can't stop thinking about the next project and the next. I've always wanted to sail a boat I built myself to Bermuda. With the WEST System it will happen.

Bottom Line Yes, I would recommend to a friend

1962 Corvette
By Gordy's from Arkansas

Verified Purchase

Great for fiberglass work on classic cars and hot rods. The cloth gives good rigidity for body lines and structure. Glass work is always messy so thats really the only con.

Bottom Line Yes, I would recommend to a friend
