I grew up spraying wd40 under the cowl of our '77 merc 115hp. Made it look real good but that was 30 years ago, is there anything else out there that is better? I have heard that wd40 could hurt the wire insulation and rubber parts although I have never really seen this in person. What are the negatives to silicon spray. I am sure this has been discussed in the past in here but can we touch on it again. Thanks
