Yes its worth it. I mean Ironlak is good paint. Just not the best. Make sure you get good caps. TroutArtsupply.com is a good site for the caps you need if they stil have them in stock.
If you want to know what colors I suggest PM me and I will send you a list of the colors I liked to most out of those I used. Mostly like all paint Yellow's and Yellow toned colors such as Lime are the thinest. But they can be used for force feilds and detail shit.
