[PSUBS-MAILIST] hard tank

[hank pronk]

Brian,
3in is pretty small for your arm,  I would dump a gallon or two  of paint in and roll her over.  That is how we used to glass line tanks.

I could possibly put a couple of 3" threaded fittings and then put a threaded plug in there, just enough room to stick my arm in and a paint brush.

Hi Hank,
Just a word of caution with that method,
The HMS Thetis was lost along with 99 persons due to paint clogging a tube
That was used to check whether there was water in the missile bay.

Hi Brian,

I don't  really need to access the inside of the tank and I was wondering how I could seal the inside somehow.  Some type of epoxy coating.  But once I do any welding it will desrtoy any coating.  Any ideas ?
