Pettit Bio-Blue Pre-Paint Cleaner #92

When it comes to scouring severely weathered and dirty abandoned Sunfish this stuff is the best thing that I've found, by far. Used according to directions along with a red scuff-pad and the results are amazing, leaving a surface that is almost ready to prime. I've also used it on a lot of other things like the dried-on lake algae on the foot of my outboard motor and it did a great job on that. I came here to check the price on a gallon because my next project is an old weathered Ranger 22 that I'll start on ASAP. As always Bio Blue will be Step One. It's important to remember that De-Waxing is the first thing you need to do; otherwise any sanding will drive any waxes or other impurities down into the scratches .

Fir dewaxing purpose you can save yourself some $. Acetone will work just as good.
