<VV> fuel tank cleansing

[cfm]

thanks dan, I called POR-15 customer service too, and essentially went ahead without repeating the Marine Clean step, leap of faith.
I coated the tank last night. It went "OK", I was a little frustrated with the ability to drain the tank, to avoid the "puddling" phenomena, but managed by turning the tank every few minutes until the "ooze" hardened up, hence avoiding the puddling.
I will say that it coated well, and the rust had been encapsulated with the POR. Again I wonder if I should double coat it, since I still have half a quart leftover? Maybe I'll save it for the other car...
Anywho, onward, to the reinstallation of, lets hope I can get her on the road soon.

It's a 3 step process.  First, wash the tank with the Marine Clean a couple
of times to remove sludge and varnish, not rust.  You're probably okay with
just a single wash if the tank wasn't really funky with varnish.  Second,
coat the tank with "Metal Ready" to etch, clean, convert the rust and leave
a zinc phosphate coating, rinse well with water and dry.  If there is still
some rust in the tank, as long as it is firm, don't worry about it the next
step will take care of that.  Finally, when the tank is dry, apply the
sealer which encapsulates the rust and prevents air and moisture from
getting to it.  That's how POR15 works, not by converting rust but by
encapsulating it so it can't breath.  It's not porous.

It'll work, trust me!!  Stuff is great.
