On the side of my boat I have a chip about the size of a quarter that I am afraid may become worse while boating. Is there a fix for this, any suggestions would be great. Thanks
No, Marine Tex is sold at any good marine store. West, Boater's World,etc.
The Marine Tex is epoxy based so if you want to tint it you will need your tinting medium to be epoxy compatible. http://www.marinetex.com/marinetexepoxyputty.html
As with any color there will always be the 'fade factor' that cannot be duplicated from any source supplying you with an original factory touch up kit.
WM and others carry a gel coat repair kit that has tubes of colors that you can mix yourself to your desired color.
