i didnt wet mine, maybe ill give it a go next time....
yea, they prob dont reccomend it for glossy surfaces coz it will take the shine off( i did it on a gloss balck and afterwards it was a dull black, somewhere betwwen flat and semigloss), but for rubbing between coats i really liked it ( i cant find polishing cloths anywhere here, so i have to improvise.. but knowing my luck, as soon as i order them from micromark and pay my money, then i KNOW i will find one here, and prob for alot cheaper :) ...)
i was using them to rub down tamiya syntheic laquers btw...
