Here is another thing about metal Ready and Marine Clean.
Quote: "Does metal that`s been cleaned with marine Clean have to be treated with Metal Ready rust remover/preprimer before gas tank sealer or POR-15 rust preventative paint can be used"?
YES. Marine Clean is a powerful caustic solution that leaves an alkaline finish on metal. An acid finish takes paint better because it etches the metal and gives it a surface profile with "tooth" and the proper PH for adhesion. Our metal Ready rust remover/primer is the perfect prep to use on any surface that`s been cleaned with Marine Clean first".
Now what you are going to do is sand it smooth first. I think if you use marine Clean to wipe it down, you should use a cloth with clean water to wipe up any residue the MC might leave. You wouldn`t have to use the MR, since it is for bare metal/rust.
OK, now we need pictures, this group lives for pictures.
