I have made a few poly boards but wanted to try epoxy. I made this 10 ft board. Used 1.5 gallon set of Resin Research Epoxy with additive F. Used almost every drop of the resin to get all the cloth wetted out, hotcoated and glossed. Here are the pros and cons that I found when working with the epoxy.
PROS:
Liked the extra time available to wet out the cloth and get all the bubbles and wrinkles out.
Light weight (lighhtest longboard I have made to date.)
Reduced smell.
Use of additive F allowed sanding just like poly.
CONS:
Long cure time (alot of this was due to the colder weather, about 6-8 hours per side)
Cost $
Not sure how others are able to strech their epoxy resin so far. By the time I got to the last gloss coat I was almost out of resin. Next time I will make sure it’s warmer and/or warm the resin. I think the cold weather caused the resin to be too thick so could not easily saturate the cloth.
Resin not locally available (have to mail away for it, but must admit, Greg was very prompt on getting the order out to me).
Will I try another epoxy board in the future - no doubt about it, yes!

Not sure what you did but i EASILY did a 9’0" and a 6’8" with some leftover in the gallon set.
Did you use the amount Greg recomended?
Did you pull the resin stringer out to the laps and paint it on? Do not use the waterfall method that most people use with poly.
Here are the amounts that Greg recommended for a 9 foot board:
27 oz bottom laminate
33 oz deck laminate
30 oz. total hotcoat
24 oz total gloss coat
total recommended = 114 oz. for a 9 foot board
Resin amounts that I used for a 10’2" board with a 2X6 top and 1X6 + fin patch bottom:
36 oz bottom (ran out and mixed an additional 12 oz for laps) total 48 oz
42 oz deck (ran out and mixed an additional 8 oz for laps) total 50 oz.
36 oz hotcoat
30 oz gloss
3 oz fin box install
total used = 167 oz for my 10’2" board
I think that if I had warmed up the resin prior to laminating I could have gotten by with a lot less resin. Most of the difficulty came with trying to wet the laps. I had to mix more resin and I did end up using a brush on the laps.
Overall, it was pretty easy to work with and I think I will be able to get closer to Greg’s recommended amounts next time.
You can warm your Part A up in microwave. 15-20 secs to improve the viscocity, then add the Part B and Add F. You will get better with your vol. estimates the more you use epoxy and eventually your excess will be drops and drips not cups.
i am just finishing up my first epoxy as well. I followed gregs directions to a T with resin amount for my 6-8 and i still have about 3/4 of my 1.5 gallon set left. I am glossing coating now. i will post some pics when its completed.
