It just hit me as i've been thinking of getting my tank painted. Someone asked the tank liner a while back, but i'm not sure of the answer. What if you were to spend the $600 or more to have this done, then your tank liner began peeling ! If it's warranteed then you're out $600. If not, more like $1200 ! Someone asked about the newer lining they now use, and i think i have that. But i wonder how many have had a problem with it. I haven't noticed any yet. But thinking about this scares me when considering having it painted. And for the job i want it's looking more like a minimum of $800. That could be devistating if the liner starts peeling and is unfixable ! I guess you could deal with the liner chips by removing the petcock every so often and cleaning it out. But what would be the consequence of using a tank thats bare inside? Rust?
