With all the detailing knowledge here, maybe some of you could share some tips/tricks. I have one. Sometimes its a little difficult to put protectant on the plastic cowl in certain spots where the wipers are. I just put a white sock over my hand, sprayed the protectant on the sock. Getting to every little nook and cranny was easy because you can move your fingers around. I was using 303 spray. Might be worthless to some but for me I thought it was the easiest way.
