OK.... not really wanting to upset anyone....but ....It's not rocket science. Shake the darn can and spray. I like the sawzall shaker but by the time you take it out(remove hose clamps) contents could have settled...I haven't used but understand the principle...but what happened with just shaking...it's been used forever....I used straight out of the can Rustoleum Hammertone on my heater, shaken and paint looks ok and I'm pretty anal..If it appears to have acne...wet sand and clear coat....Sorry beat a horse to death..,,,or step on toes...I'm all for learning. I'm all for helping and trying new things....but sooner or later things seem to run rampant...
