Made sure all vinegar was rinsed off. Did that about a month ago. Yes the boat has oxidized some but Prior to applying sealant or fairing compound I wire brushed with a 4 inch grinder that is equipped with a stainless brush. Followed with alcohol. After all the stuff I have used on the boat cures completely plan on a float test. Then I will follow with a white vinegar wash prior to priming. If you have pits and corrosion I highly recommend that you use a wire brush and remove all the white powder and black stuff. Get it to shine. Any corrosion left behind will continue to screw up the aluminum. Then etch it. Hope this helps.</p></blockquote><p></p>
