rhartmaier - I got the Mar-Hyde 3811 from the local parts store ( jobers ) they had the best price. 2 cans for $32. Amazon wanted $40 EACH. Keep in mind these cans always go bad at 25-30% left in the can and stop spraying smoothly. So if you think 1 is enough buy two. Need two? Buy 3 etc...
Also whatever you are spraying do it vertically. They suck spraying on a horizontal surface. The like to drop puddles on the piece you are working on and just generally drip. I did my side mouldings on a custom set of bucks to hold them vertically. Only way I could get an even finish.
When I sprayed the wipers I hung them on wire and just held them out in front of me. Then after a coat I would hang to flash for 10-15 minutes then apply another coat. The can says scuff with 3M scotchbright and do 2 coats. Nuh-uhh. 5-7 thin coats works best. Been there done that multiple times this past summer.
