This stuff is like water. Its better than nothin but to me its useless specially wd40. CRC is the better of the two, but I use a quality product called Corrosion X. Use it once and tell me you don't see a difference.Preventable maintenance would be to spray the powerhead down with CRC at the time of winterization. We spray all our motors down with CRC/ WD40 mix.
Are you talking bolt heads on the heads?? Explain better which bolts..I have notices around some of the nuts on the bottom of the powerhead have that white powdery corrosion on them, what is the best way to treat it and preventable maintenance:huh:

She could be "making salt" caused by running too hot. If the water jackets are getting clogged with salt this could be causing what you are seeing.. Are you seeing any salt around the edges of the head gaskets?
What engine and how old is she?
Personally I think Corroision X or Block is just over priced CRC 6-56. I've never seen much difference between them except they are three times the price as CRC.. You spray your engine powerhead down top to bottom once a month in the season with CRC and you'll never have corrosion problems.. And quit buying it in the spray can....buy it by the gallon and use a hand sprayer.
Go to any hobby shop and for 30 bucks you can buy a infared heat gun. These are cheap units they use to check little nitro gas engines when they are breaking them in.These are the headbolts on a 2001 Merc Optimax, mainly the two bolts inside the cowling at the bottom, it looks like salt build up, I have the digital interface and it always says the motor temp is good and when I check the actual temp its about 120.
I have to look at the gasket between thepower head and body, I do not think there was anything, I will take a few snaps and get them up.
