Shipping cost is high, so choice comes down to what you can buy local.

For me, itís Old No7 from Greenroom and Resin Research.

I know a guy who had issues with Entropy. Skin issues.

This is what I use, and most of the glasser's in the surf getto use. You want the UV inhibitor.

I'm a Resin Research 2000 fan, though I use what I can get. I've got a gallon of Pro Glass I'm working through that I won't try again. The viscosity is high and the slightest drop in temperature turns it to paste. That said, as soon as I warm it up it's fine and its worked even when I screwed up the ratios a little.

I used Fiberglass Hawaii aluzine and had so so results. I started with RR.

Last few boards Iíve ised this and love it. Seems very close to RR and works great. Hot coats are perfect with a little dose of additive F.

Also, price is really unbeatable if youíre on the west coast. Currently $88 for 1.5 gallon kit.

I've been using west systems 105/206 because that's what I used forever working on boats.  I know very little about making surfboards - what's everyone's opinion on this epoxy?

It's good stuff. I have a few gallons of West in Maui. I like the pump proportioning equipment, though the pumps need a priming bypass that doesn't waste resin or hardener unless you go through a bunch of acrobatics. The resin itself seems good. I don't think it sands very well unless you bake the parts a while to get every bit polymerized. RR is a lot more forgiving in that regard.

I have tried:
AdTech ProBuild-available locally during the week, no brighteners, got me hooked on epoxy.
Resin Research Kwik Kick-broad user base and email/online info, easy to order and use, haven't ordered recently.
Greenroom Old No. 7-Came recommended by a kick-ass glasser, easiest to use, no need for Add F. Good email/phone tech support, haven't ordered recently.
CPD 4245-least expensive @ 7.5 gal minimum, slower cure, no brighteners. Locally made, same company as MAS/Endurance.

I am down to about a pint of each RR,GR, and CPD and nothing newer than 3 years old. Did some repairs with GR and lams on the 9-footer with CPD and was pleased. I learned how to de-crystallize the raw resin components if they stiffen up. Buddy says I can mix and match since they are all 2R:1H by volume.  I considered doing a test panel for wear and UV resistance for them but then get tripped up by methods and materials and the fact that I should try some West and a couple others to balance out board vs boat style epoxies. I mostly measure by weight 100R:43-45H per mfgr's formula.

I first used Tap plastics marine grade epoxy (fast) (20 years ago). 
Plus: Had a local store, it is strong, easy to work with
Minus: can only use in warm weather, turns amber with time, not good for hot coats, no uv protection.

Then I tried West System epoxy resin from West Marine (fast) (10 years ago).
Plus: Had a local store, it is strong, easy to work with
Minus: can only use in warm weather, turns yellow with time, not good for hot coats, no uv protection

I have already decided that my next purchase will be Resin Research (that is what L41 uses) because of the uv protection.

That seems a little high for a quart kit unless it is being shipped globally. Going back to DW's comments about buying locally when possible. What is your location?

Sean,
Try calling Basham's Factory and Surf Shop.  (949) 361-2203  They sell RR CE. They have a 55 gal drum of that and the hardener. They package them in generic bottles. They can probably ship directly to you. They still answer the phone.

I am in the Midwest. I forget that all of California is not south, on the coast, or a stones's throw from a surf shop...but then again neither am I.
Seems like you should be able to get a three quart kit shipped for 100-110 and 1.5 gallons for a little more or do the Apex deal the Cowboy mentioned.
