    Hi guys, I am refinishing some gelcoat on my boat. Any suggestions on what kind of dye I should use when sanding with the DA?

    Welcome to the forum

    No dye should be used when sanding gelcoat with a DA.

    Exactly what is wrong with the gelcoat that it needs refinishing?
    Are you repairing chipped, scraped or cracked gelcoat?
    Or, simply restoring lost gloss?

    Pictures say a million words.

    I think there is a misunderstanding....Let me re-phrase. I am re-fairing the bottom of a one design dinghy. I have gone through the whole process multiple times so I know how it works. To keep track of what has been sanded using a DA, many people use an ink diluted in acetone. I am asking for suggestions on the ink used to track sections on sanding.

    Now I get the picture.

    Try using cheap spray paint. Quickly mist a coat of contrasting color.

    Obviously not a boat, but an example of rattle can mist coat. If you use more than one can it is too thick.

    I highly recumend switching to longboards for fairing.
