Fuel tank priming

Did anyone prime the backside of the tank baffles or the outside of the end ribs? Im debating on this one.

Boy, I'm glad you brought that up! I didn't do on first tank, but I'm going to on this tank I just finished. There are places where I roughed up the baffle and end ribs on the tank for the proseal stick. I going to hit those spots with some primer.

I primed mine, but then again I primed everything. I also alodined the inside of the tank skins and the internal ribs.

Yup, like Paul said.

I alodined the inards, and primed the outside bits.

I made a mess with the skins and alodine. Tried to brush it on ... like the alodine instructions say you can do ... but it made ugly stains on the skins.

Anything I could dip in the alodine worked fine.

All -

I did not prime anything on the tanks except the Z-brackets.
.. and when I went to clean the excess pro-seal after I was done with the tanks - some of the primer came off these.

But I've primed EVERYTHING else (inside skins, ribs, stiffners, etc.)

wouldn't the primer dissolve in fuel? doesn't sound like a good thing!

Ian, I think Spike is inquirying about priming the extermnal portions after the tanks are complete.

I did not prime mine and don;t plan on it though I have primed everything else. I figure if I ever need to I can just build a couple more tanks 30 years from now.

I alodined the Z-brackets and the T-405 BHFTABs (big honkin' fuel tank attach brackets) with a Touch-n-Prep pen. The Z-brackets also got primed except for the surfaces that would be Prosealed.
