I own a 18 ft aluminum boat. i had a problem with electralasys which caused some pitting in the bilge area. I sandblasted the bilge area and painted it with gluv-it also mounted zinc. also had the boat rewired. I was wondering if it would be safe to use it on saltwater and then rinse it out after each time on the salt. i was wondering if this would bring back the pitting if i used it on the salt water.
