Re: my stringer job 19' Cobia with pics
A new stringer would be best, your in there and have done all the work to get there, with the work you will do trying to sister everything you probably won't save a lot of time and the old wood will be there as a failure point in the future and may even encourage the new wood to decay quicker.
Use your safety equiptment!
Protect your lungs, eye's and skin with a respirator, goggles, long sleeve shirt, and gloves while grinding, vaccuming, sweeping, etc. max!
