I really like Advantage 325 Hi Build Primer, because it builds nicely and is really easy to sand. Evercoat makes a budget filler that, honestly, is just as good as the stuff twice as expensive, called Z Grip. I also use Evercoat kitty Hair for the buildup on doors. Dura gold paper, and blocks. Getting the paint from Auto Paint HQ. They are in St Louis area, which is only a few hours away for me.
