    I plan on gutting my entire boat down to the bare hull as to replace the stringers and decks.
    I'd like to do this over a few weeks time, and rip out all the rot, then start to grind the entire hull. However, I understand after the hull has been grinded/sanded down to bare, fresh glass, it needs to be coated asap as to not let moisture and impurities into that new surface. I've read about peel ply but I don't think that'd apply since im not applying new glass right away.

    My question is, is there another way to seal off the freshly prepped glass, so I could leave it for a few days/week or so, this way I can work on the boat a little bit at a time?

    I thought about putting a fresh coat of resin on within a few hours of grinding each area, but even then when I go back to apply new layers of glass eventually, I'll need to grind and prep that few day/week old resin.
    Or am I just left having to do the boat in small sections so I can apply new glass and resin to the newly prepped area a day or so at a time?

    Thanks for any input!

    Boats are routinely peeled, washed, and left to sit for a year to dry out. Not sure what the issue is. There will be some surface prep to do before reglassing, but not a huge deal. Just drape the area to keep contact to a minimum.

    There is no problem on waiting. If the boat gets exposed to UV for several months, the resin will start to degrade, but that shouldn't be a problem for you.

    Dust, dirt and other contiminates can cause problems, but these are environmental issues, not really time related.
