Hey any chemists on here?

I tried this stuff when the old lews store was pushing it and everyone talked about how good it was.  I found it did not work what so ever on my engine, and it really isnt horrible with water spots.

I have found that if you hit enough brush with the jet boat while drifting and fishing, it rubs the water spots off the motor.

I'm not a chemist, but I've restored more outboards than anyone in the Midwest.  I can assure you that water spots either wipe right off with a light scrub,.....or they continue beyond the clear, into the paint at least 1/4 its thickness.     

You don't, however, need to get them completely out.  Paint, clear coat, and wax adheres to calcium just fine as long as it's smooth, clean,  and you can't feel it.      

They also do not detract from a used motors value one little bit.     🙂

I read the label on that stuff.  It said no rinsing required so I sprayed it and wiped it off, no water spots .  I noticed a bottle of 303 that I bought to use on trailer tires.  I sprayed a coat of it then wiped the motor again.  Clean as a whistle and shiny.  Maybe I will have to drag the hose to the boat bay less often.
