I got a painting kit from Stew Mac that included filler so I figured I may as well use it. I figure it can't hurt since I'm doing a solid metallic color anyway.
Good to know I don't need to wrap the binding pre-filler. It would be a little frustrating to have to do it once for the filler and another time for the actual paint.
Thanks for the tips! I would have never thought to use drywall compound. Always appreciate you!
Next stop: figuring out a creative way to build a painting stand for my spray this weekend if the weather holds.
