[quote=MN3]if you don't have a lot of experience i would look at youtube for a while for tips and techniques

The west system videos with the english guy are fantastic

(there are 3 in this series)  - [url=https://www.youtube.com/watch?v=_5uqyfiaufU]https://www.youtube.com/watch?v=_5uqyfiaufU[/url]

i would definitely turn the boat upside down and let it dry out 100% if there is any chance of moisture

I would paper/mask off all areas that are close to your repair area

if you think you may wear down this area again in the future you may consider using west system 422 Barrier Coat Additive  or similar
"Barrier Coat Additive is a proprietary blend designed to further improve cured epoxy’s moisture exclusion effectiveness. 422 is used as a barrier coating additive to help prevent gelcoat blistering in polyester fiberglass boats. 422 also increases the epoxy’s abrasion resistance. Cures to a light gray color." -[url]https://www.westsystem.com/422-barrier-coat-additive/[/url]

fairing the skegs should be pretty easy but when you move forward and the skegs blend into the bow area it may be a little trickier . be sure to mask off the area you are going to work in.

it gets tricky when you are fairing off the new gelcoat - it can be hard to see where it ends and the old gelcoat starts (you don't want to take off any extra)

I did a bottom job recently and found "brushing" on gelcoat to be futile. 
the tip and roll method is probably much better but requires 2 people and still is not a perfect system<em>Edited by MN3 on Jan 23, 2020 - 02:12 PM.</em> [/quote]
