  • everytime i ask this question to different people i never i get a straight answer, so once & for all-
    how exactly does uv light/sunlight affect eps boards? & is it true that exposure over time breaks down the material to where it could snap/break/ become brittle? the custom fish i had made back in march happens to be eps. ridden it countless times now in rk,lb & some spots in nj & since its seen its share of light. it was made with 6oz glass top & bottom & could stop a bullet its so strong. its got its pressure dings & whatnot, but its been put through hell incl running over the sticks a few times. so what im wondering is it that its glassed a bit thicker than most & thats why i havent seen any deterioration or cracks? or is it too "new" of a board to see any effects of sunlight damage?

  • it's not a vampire is it? because if you didn't actually make it into a vampire, it should be fine.

  • March was less than a year ago so you probably don't notice anything yet and rightly so. Put a solid color sticker on the board and pull it off in two years, then you will see a difference. I've had a clear coat log for 5 years now that is always in the water (with or without me) and it is recently becoming apparent to me that it's getting brown.

    Any plastic or fabric will get brittle in direct sunlight over an extended time.

  • I don't know of anything specifically bad about epoxy and sun, but think of the dash board of an old car, or the cracked vynal seat. Sun cracked and the foam is all brittle.

  • The new epoxy that glassers use is different then say the "Loher" epoxy of the 70's
    The yellowing and brittle qualitys are all but gone.
    There is another version of epoxy coming out as well that is even stronger and better.

    Your 3 basic epoxy models are
    Molded, think surftech
    cc/Hand shaped think local
    And cc/hand shaped but also useing a commpression system (vacum bag) Think firewire
