I was snooping around a Mitre10 shop yesterday and found a product that may well be exactly what I'm after.....
Loads of grip bare-foot / sand-shoes / wetsuit-booties without the harsh sandpaper finish wink

can be applied either by brush or roller.....

dries in 4~6 hours

wash-up with water

comes in 1, 4, & 10lit cans..... ($42 for a 1lit can but I think I can haggle that back to atleast $30 a can wink )

available in 12 "natural colors"..... BUT.....
if you buy the 'base-white' it can easily be tinted to any color you want

drop into your local hardware store and grab a info card (much like a paint color chart), it has a "sample" on the inside of the actual product

booklet and website both say its ideal for outside and marine enviroments smile

anyone ever tried it ???
