Hi, I just was looking at Google for a good price on epoxies and I came up with this web site, http://www.epoxyproducts.com/m192.html I am kind of new in the trade, so if you have a chance,please take a look and let me know what you think. Thanks

I bought the same company's "basic no-blush" product, but I haven't had a chance to try it yet (haven't run out of the more expensive West System stuff).

According to an engineer friend, all companies buy epoxy from relatively few manufacturers; most just slap their names on them. We'll see.

I'm no expert on epoxy, but I will throw in a couple of pennies worth.

I've used 2 different brands so far. One was System 3 and it performed well (except for the price). After that I decieded to use an off brand that was half the price. Now it sometimes kicks off good and other times I can't get it to set. One time I had to completly clean it off of my boat and re-apply. It didn't kick off after several weeks.

Next time I will try RAKA (http://www.raka.com) it seems to be the both of best worlds, good price and good epoxy. I haven't used any yet but the folks that do swear by it.

Chad, can you enlighten us a bit more? Epoxy is expensive stuff and so is our time and labor. Under what conditions did that "off brand" epoxy kick off and again what were the conditions when it would not? Knowing that might help us understand what happened and how to fix it. After all, it might not be the "brand."

Second, and most important, what brand was this off brand, or where did you get it? I don't want to do any bashing or selling of anybody's product, but I do want to know what to make a good decision when it comes to epoxy. My first boat was built with polyester resin - not recommended, but it worked! :D

The epoxy came from US Composites at:


I got a 3:1 thin epoxy and a 1:1 thick (for laminating). Un-thickned the 3:1 does not always kick off good. It don't matter what the circumstances. Once I thought it was my mixing fault but after several attempts I determined it is not me. If you mix with a filler it kicks off with no problem and it makes a great filler. The 1:1 thick stuff works great as a laminating epoxy (though pretty thick) and I've never had any problems with it.

I've also heard that there is only a few manufacture of epoxy, but it may be like Budweiser & Bush beer. Where Budweiser is the good stuff and Bush is what is left in the bottom of the barrel. For my moneys worth I will not buy from them again. The aggrivation of not trusting it to kick is not worth the savings.

Discaimer: These are the views of one customer and not neccerally the views of Wooden Boat or the "Committie"


p.s. They also don't respond to e-mails when you have questions about their product.

Check out Fiberglass Coatings Inc, www.FGCI.com. (http://www.FGCI.com.) Many of us have been using their products for years with no problems. I've used perhaps 50 gallons of it over the last 12-15 years, and never once had a problem. I've used twenty gallons so far on my current project-- http://personal.riverusers.com/~emkay/puffwelcome.html --and am getting ready to order another ten gallon batch.

They offer a no-blush base laminating/coating resin, and you can choose the activator ('hardener') to suit--from 1:1 (my favorite) up thru 2:1, 3:1, 4:1 and 5:1--all the same resin, just different activators.

They also offer a 1:1 penetrating epoxy, not as water-thin as CPES, but not as diluted either.

The 1:1 laminating resin costs about $62 for a two gallon kit.

I'll go along with Mike Kerrs opinion of Fiberglass Coatings Inc. I would recommend their 3:1 ratio for highest strength. They have a very wide range of tools and accessories that are difficult or expensive to find at other suppliers.

i'm using their(FGCI) superbond 1to1 on a glued lap canoe and i really like it. i would probably go with their medium cure catalyst next time. in my 68deg. shop each batch goes off at about 5 hours. a little longer than needed. i tried heating it but other than making it a little bit easier to flow it still went off at 5 hours like clockwork. the price was great. their 2 quart kit with shipping was $32.00 mixing was easy without pumps and the mix is like vasaline.
