The best way to fair is to use a lead pencil and determine fill amounts and write on the hull. For example, +1/8", 0, +1/16"

This is the best advice I never got.

Fill tools must not be too flimsy; this is not the same as water based joint compounds.

Do not assume typical sheetrocker methods work; they don't. A sheetrocker fills corners first. This is a botch.

Fill all the deeper areas first.

Make sure to use long enough tools to determine low spots.

Generally, the bottom is faired on 45 degree angles to the chine. But make sure the angle makes sense.

OK, I'll work in that direction on those angles. Thanks!

Just a general guide; you'll need to run the tool and check spacings. I use angle iron screwed to wood.

Should I start building an edge on the chine immediately or a bit later in the fairing process? Is there a good technique for this?

You can do it as you go.. No technique for the chine. You can make a mould on the transom if u r creative.

I squared off the transom top to make it look pro.

The main thing is don't ever apply fairing compounds over dusty stuff. Dust is the enemy.

I kinda like to use fiber on tbe transom edge. Figure it less likely to chip.

Agree with fallguy do it as you go and fair both the bottom and the sides. Don't forget once you get your chines and transom sharp you will need to round them over a little, like an 1/8" so that the paint will hold on. Paint will tend to flake off a sharp chine.

Yup, crazy as it is break those sharpened edges or paint will go ultra thin on you.
