MAS vs. WEST epoxy

[Tahiti_Tim]

I've noticed Boaters World, etc. are now pushing MAS epoxies.

Any thoughts and/or experiences on MAS vs. WEST?


pros: I've heard that it is more human friendly (lower VOCs, lower skin toxicity, etc.)

cons: It's more pricey than WEST.

Holy cow! More pricy than West! I didn't know it was possible!

I use alot of West Sys. Epoxy because I like its cure rates. I mostly use it in the warmer months. When I have to...

Otherwise I use epoxy resin from FGCI (Fiberglass Coatings Inc.). Their stuff is 4X less than the price of West System and its physical properties are better than West. The only problem is that its pot life is really quick for their 4:1 and 5:1 resins. Their 2:1 resin has a really nice working time though.

The guys up here use MAS, they love it.

I like west, but I am sure that my supplier is cheeper with MAS.

Hey guys,

I have just finished a transom, stringer, floor rebuild of a 1978 Glastron HPV 175 bassboat and used 15 gallons of Paul Omans
Basic No Blush 2 epoxy, Mixes 2:1 ratio, approx. $140.00 for a 3 gallon kit includes shipping.

Paul Oman is a specialty epoxy formulator in the New England area, personal service, go to epoxyproducts.com; you will be glad you did. He also has putty, thickeners, and several epoxy types.

When I did my transom with the fast Wests, it took about a couple minutes to kick in a small amount, not deep in container at near 90F. If I had to mix larger amout or more time I did it in the morning at ~65-70F and it was easily double or more time (& keep the epoxy cans cool). If deep in container it still warmed and went pretty fast. I can't complain about the quality/performance of the stuff at all; even on bare unsanded gel it stuck hard (one way I tested it for stick to old materials) and two years of me jumping on motor all is good...in a bayliner transom that is not the stoutest thing around. Laquer thinner cleaned it much better than the recommended acetone on brushes. Used just over half a gallon on this smaller center transom and a little stringer patching.
