I've got a little more wet area on my cabin top than I thought. My approach is to tackle this a little at a time. IOW, repair a portion at a time rather than tackle the entire area. I know this isn't ideal but the deck is very solid in the wet area(there is no rot, just dampness). I will get to the entire area over the summer but I've got a lot of other things I'm doing and I'm hoping to get launched by mid May. Is there any downside to this approach?
