Quick oxalic acid question
 

http://www.hardwarestore.com/media/p...0_front200.jpg

This is at my local Ace. Is it pure oxalic acid? If not, how much per gallon have you guys used? I read through the label and there wasn't a listed concentration or something that stated it was pure. I'm assuming it is....from shaking it, it seems like a crystallized form. I don't want to order from ebay if i don't have to. If it is pure, its about a teaspoon per gallon for a .2% concentration correct?

Im spraying framesaver inside the tubes after, but it seems to me like a spray can wouldn't really coat the whole inside of the tubes....do i just spray a ton of it in there? any tips?

Does the outside of the frame need to be neutralized w/ just water? a quick spray down? the frame is completely stripped of paint, so it will be off to an autobody guy for paint and primer after.

Thanks for all the help! making major progress on a 70's frejus so far from the help on here.

yes

The answer was a whole lot quicker than the question
