i use a high lacqure paint or clear coat when i paint tile, and right after i apply the final coat i sprinkle a very light amount of very fine grit sand. it doesnt take much but it really helps with slipping on wet tile. and it doesnt gouge your feet as long as you dont go overkill with the grit or the ammount.
ever made that statement ".....when pigs fly" well better get to what ever it was you said you'd do lol.

kick is kick, i started with a 410 then my next gun was a 410 .22 over under, the smaller gauge just teaches him to shoot better. teaches him to be more accurate.
