Well thankfully none of us have fiberglass tanks and they are mostly in older boats.

There was a guy here when this first came out with a Bertram size? But to tear up the teak deck and replace the tank was $10,000!! :o

As far as the gas not lasting all winter, I started my boat and it is fine so far!! My friend filled his tank added stabil and used it all with out any issues?

But I have always tried to get rid of all my gas before winter, for 15 years now!!

Any who the biggest problem with this gas IMO is that it mixes with water and there for makes your water separator useless! Unless you have a ton of water.
