If I can use adam's tutorial for painting on my pep armor and make it work, then you can make it work on a westerfield suit.
I just think a stormtrooper kit for 350 is better than buying a westerfield mc kit for 700, both unfinished.
But, westerfield's suit is good, so it depends on what you want. If you can paint it good, you can "improve" the quality of their armor.
usually people who get kits from westerfield just paint the suit 1 color, they dont battle damage it or anything, this makes the suit look cheap, a good paintjob can make a suit look 1 million bucks, especially when it comes time you have a better suit, and sell the old one on ebay..........then there comes the big bucks.
