Working on a resto for a 1988 Imperial 200. I just got the port stringers glassed in today (15' on a 20' boat), but am relatively unhappy with the amount of bubbles I got in the 1708. I tabbed in 3/4" marine plywood with 6' of 1708, and then followed with another complete wrap of the stringers (2 on port side) with another layer of 1708. Unfortunately the biaxial got a bubble for the first inch from the top on either end despite me routering a round into the top, but overnight I noticed that there were quite a few quarter sized bubbles in the stringers themselves.
I am not too worried about the tops of the stringers, as those should not be providing the hull any support. I am a little unclear on what to do with the main body of the stringers, does anyone have any guidance on what is acceptable versus not? Looking at how the boat lasted 20 years (no bedding for stringers, no fiberglass all the way around in alot of places) I am not worried, but want to make pretty sure I don't regret not grinding them out. I am using MEKP catalyzed B-440 polyester from US composites if it makes a difference, many thanks in advance

I'm just glad I don't do this for a living---I'd starve!!
