Speedsurfing BLOG test, polished fin how does that feel?

Select SL7 polishedpolished fin how does that feel?
  • Slippery...
  • Not very safe @ low speed... It looks nice, and it is way easier to detect any flaw in the vin profile!!
  • It takes more energy to make the board plane
  • I have customized a few select fins by painting==> polish them==> sand them with sandpaper 600
  • So far sandpaper 600 is the finest that worked for me.
  • So far polished fins have proven me not to be significant faster.

  1. Hi Erik,

    Is sanding with 600 the best result you got? Was it wet or dry? In which direction do you sand?

    greetings Robert

  2. I have sanded almost all my fins with 600 wet. I am sanding in the lenght direction of the fin
