Re: DIY tank... even if you can't weld
This thread reminds me that aircraft wings function as tanks by fixing the skin of the wing to the skeleton, and sealing the gaps with either fluid or paste two part sealants.
These can often be acquired cheaply from aerospace suppliers when close to or after expiry date for aircraft use. There's nothing wrong with the product, but it's just not guaranteed to 50,000 feet and 600mph any more.
A WORD OF WARNING: ALWAYS ASK FOR HEALTH AND SAFETY SHEETS, AND FOLLOW INSTRUCTIONS. This stuff pays for being supreme as sealant by being toxic until properly mixed.
