The striping problems are due to the reducer drying to fast...not the way you are spraying it. I have used the BB before...reduce it with a slow evap reducer and you should see a difference. Also...this stuff looks like crap as it is drying....hang tight and wait for the entire surface to dry, you'll be very suprised.
I keep a gallon of it around for various things. I painted the frame on my project S10 with it, and I also painted my beatup Ranger with it after my bro-in law got all drunked up and painted the entire truck with Kentucky Chrome spray paint
