We have used Phix Doctor products in the shop for years due to having virtually no issues with them. This is a sun powered Mini DuraResin repair kit for dings on your board.
The DuraResin is a pre mixed repair resin that works on Polyester or Epoxy boards and is sun (UV) cured. To use simply clean out your ding, sand to key it up and add DuraResin into the ding. Tape over the supplied plastic sheet to flatten out and put it in the sun. After about 10 minutes (or until hard) it is ready to use, perfect to save your session.
The Mini pack gives you 1 fl oz of DuraResin, enough for several small dings or a large one, 2 x plastic sheet 100mm x 75mm, a piece of sand paper with two different grits, 2 x wooden sticks and a sticker.
