Folks, given the concerns raised with these 1992 tanks I've made the decision to replace both tanks (13 gal and 6 gal) and recover both wings. It will be a winter project I can do in my basement.

I'm looking for any builder's websites that I can reference on this journey. Any thoughts on what to replace the 25 year old fabric with, would also be appreciated. This will be all new to me, but I'm looking forward to getting to know "Dorothy" in a more personal way.

Thanks for all the advice and encouragement thus far.

Best regards!
