Murrays doesn't really give enough information in their catalog for a definitive answer. The cost of the hardener and resin is about $56. The mixing buckets are cheap ( > $1). Gloves, Spreaders and popsicle sticks are also chump change.
But getting just the right amount of cloth would be tough. It looks like they're got a couple pieces of 9oz tape. How long? Don't know. But a 50 yard roll would be overkill and costs about $78. A couple of 10ft pieces are $13.25 each. Some places will cut pieces to length. And they may have a chunk of 12oz in there too. Hard to tell.
So yeah... It's probably a decent deal. They're definitely using good quality epoxy (West is what we sell too). I'm going to ASSume that they're getting cloth from West too, and sending enough to to both hulls. But you'll have to call them to confirm.
Personally, I'd want a slower hardener than what I think they're shipping. 205 is good stuff, but might kick off too quickly for most people on a big job. Especially in warmer climates. I'd go for the 206 or even 209 hardener. And I'd want some filler to add to the mix to keep repair weight down - probably 404 High Density.
As far as Saran Wrap, I've used it, packing tape and stiff plastic to get a smoother first pass by covering the repaired area while it's still tacky. Saran Wrap will sand out easily. With stiffer plastic, I hose it down with no-stick spray (like PAM) then let it "dry" before I lay it on the repair.
If you're not familiar with West System, they make great stuff and have a rocking website. Check out some of their technique and project articles @
