I recently bought a US Box fin and it is a bit loose in the fin box. I was just wondering what the best material is for making a shim or any other way to fix the problem.
You can use an empty can of coke!
A pair if scissors and an Ali can works fine.
Just watch you don't cut your fingers!

I ended up using the plastic from the plastic milk cartons and it took a bit of fiddling to get it into place but now it seems to work a treat!!! Thanks again for your help
