    Hi. This Dark Grey material was used on the inside deck.The same material in flat form without the bumps was used on the main and upper decks.The areas were painted with Interlux Perfection 2 Part Epoxy Paint.What is this Dark Grey material? Besides a Rorschach test IMG_8806 (1).jpg View attachment 74260

    John -Thank you for the advice.The Hull and House exterior are Gel coat.All other parts are painted.Blasting would be a challenge! Results are generally always greatbut OH what a Pita!
    Do you off hand know if this Dark Grey material has a "name" ?Thanks again.

    Looks like it was troweled on as a coating. Some kind of thickened epoxy perhaps?

    Is it sheet stock?

    Looks like coosa board.

    I used a piece here to create a block for a seacock.
    These are covered with epoxy and cloth but you can see the raw edges.

    And the Master builder from Conn. says "Looks like a pair of boobs to me ".There we go,we did not have to wait for someone more experienced to comment. A possible Rorschach fellow veteran.

    Timeline for material useage is the hull is solid fiberglass layed up in 1998. The boat was commissioned in 2001. A Dentist in his late 80's from Brick,NJ had the boat built.

    "Looks like a woven roven that was gelcoated grey, then painted." Quik Fix . Searched around and found lots of info on woven roven in comparison to Biaxel.
    Keelboater and Genius are very knowlegable on all things boat related.Does the "like" comments imply agreement with Quik Fix's answer? The "Grey Material" if it is woven roving is not compatible with the two part epoxy leading back to Blitzen's initial suggestion. Thank you all for information and suggestions.

    Just sand it with 40 grit. Angle sander or orbital if that's all you have. Get a good surface for whatever you are applying. Acetone wipe after sand. What's your plans for coating afterwards?

    Edit: I don't think perfection is an epoxy paint is it? I thought it was a two part polyurethane. Not that it matters but FYI. Before using this....if that is what you are doing. Use the primer for it would be my suggestion.
