Or do I mean procrastination? You have read many posts about sanding and fairing, and this is one more, potentially the last (for both our sakes, I hope so).
You put the faring batten on the hull, you look for deviations of more than a few millimeters. You do this in all planes. You argue with yourself what is ‘a few millimeters’. You run your hand around feeling for divets, you mark them as you find them. You fill with epoxy mixed with light-weight filler for sanding, you mistakenly vary the mix slightly from time to time, you save money with some water effected, lumpy filler. You vary the application process attempting to speed things up (troweling ridges vs multiple coats). You sand with varying electric devices, balancing the felt divets with the eyeballed fairing batten results.
Sometimes you over-sand, sometimes you under-thicken the filler. You eventually realise that everyone is correct, this is only a job for hand sanding with a long/torture board. You fight that concept. You plan to hire a fairing team. You can’t find any money for the hire of the team. You wonder where they work and how to find them. You look for more information on fairing. You beat yourself up about not being able to complete this ‘simple’ task that is holding everything up.
You try again on the long board. Your lack of upper body fitness is obvious. The rotten left shoulder bites back. You give up. You beat yourself up and try again. You end up aching and frustrated and the hull appears no better. You ask advice, you get your work inspected, you get varying answers. Everyone is telling you (the truth) that it is a personal decision.
So, you bite the metaphorical bullet, and spend four days hand sanding.
And it now looks and feels pretty good.
It may be fair now!
