Why is vinyl etch primer not waterproof......or is it?

[BarryK]

Same reason, the base clear on your new F-250 setting in the driveway is not water proof.

It breathes.

No water is not being sucked up by the paint when it rains, or you wash it but if you think it is waterproof stick the hood in water for 3-9 months with out coming up for air and you will get bubbles down to the e-coat.

That is why bottom paint is epoxy for boats that don't come out of water often.

Not sure this is even worth talking about, as most if not all acid primers become illegal first of year, as I understand it.

I know we have had a mad rush of inquiries to private label epoxy for some folks, because of the law.

I have not looked into the law, so not sure but going by what some big marketers are telling me.

Thank you Barry. Its about once a month i get into an argument with my painter about epoxy vs. self etch. he says since its a vinyl self etch its water proof and the sherwin william's tech that comes into our shop says "they used our self etch back in the 30's and 40's on all the army tanks and missiles so they didnt rust" so he goes and buys a $300 plus kit of self etch for the truck he is building. Guess the jokes on him. So after 3-6 months of sitting in the water, will the epoxy be penetrated? And as with new vehicles, what kind of primer do they use are any of them a self etch? Thanks again.
