[AJD] need for tank etch?

[greg at theoldtractorcompany.com]

I have sealed quite a few tanks and never did etch them.I think I was lucky. I just steam 
cleaned the devil out of them, let them dry for several days in the sun, then usually used two 
bottles of sealer so as to have enough liquid in the tank to swirl around. I then propped the 
tank up and drained the excess sealer back into a bottle, no need to have it 1" thick!
I have always suspected that the reason I didn't need to use an etcher is that these were very 
old and very unused tanks. Example being the one on my 1927 D. Probably hadn't run in 40 years 
so I thought this tank and the others were nearly virgin. That and I made darn sure the tank 
was 100% dry before I installed the sealer. As I've said before, the 1927 D had quite a few 
holes as big as a silver dollar and somewhere near 200 pinholes. This tank has held gas since 
1987. 
So the tank will have to come off to clean or etch it and then seal it.
