Re: oxidization?
a few suggestions
first, this is a bullitin board not a chat room..... be patient.... sometimes a reply takes a few days
second, get a jack (or some other method to get the nose in the air) on that boat so any water that makes it in can drain out or the rot inside will be far more important than the apearance on the outside
third, that looks like scum to me and not oxidation.... In that case it just neads cleaned....
Boat bottom scum, algae and other heavy residues are removed easiest with solutions created for that purpose. Star brite Instant Hull Cleaner has been formulated to remove water line and rust stains from both fiberglass and painted surfaces. To use, simply wipe or spray on, wait a minute or two, then rinse off. It's as easy as that; no rubbing or scrubbing required. BoatLIFE Hull and Bottom Cleaner is boatyard strength to remove algae stains, marine stains, scum and mineral deposits. Will even soften barnacle rings and zebra mussels. Other hull cleaners include Boat Armor Instant Boat Bottom Cleaner and Nautical Technologies Boat Bottom Cleaner. (Some hull cleaners are fairly caustic, read directions carefully before use.)
After using a heavy duty cleaner like these it is very important to wax the fiberglass to seal and protect it
oxidation on fiberglass boats is generally the result of damage caused by the sun called outgassing..... generally it ocurs on the top and not the bottom
If it was an alum boat and it really was oxidation then a thorough cleaning followed by an acid treatment with a product like trailer bright or some brand of etching wheel cleaner would disolve the oxidation and leave the alum looking a bit dull but don't use that on that f/g boat
If i need to sand it down to get rid of it then so be it but i would appreciate some alternatives
