Sealing micro-balloon fairing
It is my understanding that micro-balloon fairing loses its resistance to water penetration when sanded. This picture depicts an applied coat of sealing epoxy. No roller was used as I dumped the epoxy from a cup and spread thinly via a squeegee. Next step is to sand the epoxy with 120 grit paper.
Fairing/sanding the keel took a disportionate amount of time. I did much hand sanding on the keel and had to wrap my finger tips in duct tape when they became raw.
**Edit 03/29/2013: I have been following a boating building thread discussing the need for sealing recently applied fairing compounds. The conclusion is that applying at least a single coat of un-thickened epoxy below the water line areas is essential. If the boat is to be long term moored in the water, apply two coats of epoxy.
