1- You should not need to spray proper 316SS hose clamps as they should not rust. If you have hose clamps rusting they are not suitable for the marine environment.Well, by "go crazy" I guess I meant spray it on anything that looks like it might corrode. From what was said I guess that rubberish things not meant for fuel are best to stay away from. So for example maybe don't spray the hose clamps on the stuffing box. Any maybe not spray hose clamps on exhaust hose. How about on turnbuckles and stainless wire cables?
