on last year's project boat i used rustoleum topside paint with their non skid additive. seems to be holding up very well so far after about 15-20 fishing trips. their non skid additive was basically fine mica (sand). it's a little sharp on bare feet. for this year's boat i have been looking at Awlgrip and Interlux's additive. has anybody had any experience with them and how do they feel on bare feet? both of them are listed as polyester beads rather than mica.
