it IS a little much these days. like 40 different fat caps out there. personally i use 1 type of cap about 90% of the time for everything. i grab a few every once in awhile and clean them out and they last for months. newer paints seem thicker so it might not be as easy to clean caps if youre using ironlak or whatever cool guy paints are out there. rusto. forever!
good info by the way. i remember back when i first started toying it up i was sure i was just THAT bad because i couldnt get a can to spray THAT clean compared to what i was seeing on freights ( there was hardly a graffiti scene here at that time). i think it took me like 6 months to discover fat caps. then i realized i was just bad not terrible. haha.
