8) Glad you are getting the hang of it! Just remember that the texture can throw off your eye, and after you have worked yourself till you're blue in the face applying and sanding the quickfair as smooth as you can get it, it will still look like it isn't quite fair in spots, and that's when you want to prime, so that you can see everything in a uniform color, the minor details really pop out at you then, and become easier to touch up with the quickfair.

Hey Jamie,
Thanks for the tips! Here is what I discussed on the phone with you.
The goal here is to maximize use of Quick Fair and reduce sanding.
First I measure the distance between the strakes. It was 10.375". Next I cut a piece of 1/16" g10 fiberglass to 3.375 x 10.25".
Image

Next I inverted a sanding block with #220 grit paper and flat sanded the working edge.
Image

After I got a nice flat surface, I beveled the edge at 20 degree or so. I had my friend Marc hole this for the picture. Just overhand the edge around 1/2" hold it down with one have and sand with the other.
Image

I mixed a 60 gram batch of Quick Fair and went to work. First I would spread a line out about a foot or so with a plastic spatula. This kinda lays a base for the g10 spatula. Once the surface is filled with the base coat, the g10 is used to evenly spread the compound into the lows.
Image

To the naked eye this first looks as fair as the second coat did on the last surface. I may have a winner here. We'll see after sanding this out. It is my hope to go directly to the metal spatula technique after sanding this application. 8)

I'm trying to catch up my reading here, but I can't find if you said why you added the strakes before fairing the bottom. Was there a reason for that?

Finished first coat on surface between the strakes. Had a tiny bit left over so I used it on the third surface.

Image

I sprayed a guide coat on opposite side panels. I decided to fair these again. This time with Quick Fair.
The boat doesn't have to be perfect but I have to like what I see.

I'm tired, I'm going home.

Yes, I did it because I used foam for the strakes. That had to be covered in fiberglass. It is my understand that you should never glass over fairing compound. I would not do it again.

Gotcha. And thanks for the answer!

If I may make a suggestion...next time fair the entire bottom. The solid surface will be easier to work with. Then you mark your lines for the chines, and grind that area back down to the glass. Install the chines & glass. You still have to fair along the chine/new glass area, but those are pretty straight lines...and the surrounding bottom is already fair.

You're right in that you don't want to glass on top of the fairing compound...but that's why you grind back down to glass in those areas afterward.

Best of luck. Your sweat will pay off in the end!

Eric I saw you asking about casters on a different thread. for what it is worth with a boat as big as yours I say go big on the casters. After the build you will always come up with another use for them. By big I am talking 8 inch. No less than 6 inch or you will be sorry.

Thanks for the tip Fuzz. I was thinking 4-6 max.
I'm moving this on a concrete shop floor, much smoother and more level than a driveway.

Here is end of the week. From keel to first strake 98% ready for primer. From strake to strake 80% ready in one pass!!
My triceps are tired as all get out so I'm gonna rest up this weekend. Read as "NO SANDING" :lol:

Image

I also sanded the bow section after I sprayed the guide coat yesterday. The paint would sand off as powder but it's loading the sandpaper.
I think I'll pick up a fresh can tomorrow, the can I have is around 2 years old. Plus it takes overnight to cure.

Close up to show how guide coat makes lows jump out at you.

Y'all have a good weekend!
