I have a twin engine gil bracket that is made from cast aluminum with a very hard baked on porcelin like paint finish.Near where the engines mount to the bracket, above the waterline, the paint is starting to bubble up.It seems to be mostly concentrated around where the engines are mounted.The paint bubbles have not broken through to the air yet.I wanted to know if anyone has had this problem and what they did to fix it.I wanted to fix it before it spread much further.<br /><br /> Thanks ...2600
