many questions about repairing/replacing stringers

[carboncow]

OK, looks likes the cabot mixes with resin fine.

EDITED:

1. We are going to buy from UScomposites. Their resin comes in thin and thick...but there is some warning about the thick not being idea for getting into cloth. Should we buy thick for doing vertical stringers and thing for everything else or will thin work for vertical with some patience and technique? Or should going with a faster dry...or just a few more drops of hardner. What is the best technique for vertical.

2. Can "peanut butter" be used about anywhere to fill a void? I have those small gaps we dug out near the edge of the sole where I need an inch of filler.

3. Liam, did you use tabing for deck work connecting to the sides or overlapping larger pieces...or just work with well cut larger pieces?
