I got the work knocked out yesterday, now it's weather. Best chance to wash her will be today! I am concerned about the cool temps though. Cracker Larry said this needs to be done on a hot day. I don't know how well it will go in the mid 70's. Plus I hope to line up a helper to mix epoxy while I lay it down.

Use something to warm up the resin. CL suggested the hot day to facilitate viscosity of the epoxy. You need it runny.

Because you are not me or fuzz don't forget:
1. Have spare roller frames with high end rollers ready to go.
2. have a heat gun ready to nuke air bubbles.
3. SIFT THE GRAPHITE
4. Do not use the very end of the cup. If you have lumps that's where they live and you will go nuts trying to remove them once they are on the hull.
5. Since you seem to love sanding, do NOT dry sand that stuff. You really need to wet sand it.
6. Use many THIN COATS instead of a few medium coats. You will be much happier with the result.
7. Don't forget the stagger your tape lines and remove tape after the epoxy sets a bit.

With a hull that size you can probably just go from coat to coat with no real pause. Tape, start at on end working toward other, pull tape, retape, start at end and work toward other, pull tape, repeat. Set aside a number of hours.

Make sure you have some small batches of straight ready to mix to preload the roller when you have to switch frames. That will save you from wasting the graphite mix.

I'm sure you'll knock this out making it look like a mirror. Can't wait to see it.

Eric, how much has it cooled off up there? Still really hot here in FL!! Jeff

I'm prepping for epoxy graphite coating on the bottom. This line is at a 10" waterline. I'll move it down a half inch at a time until I get to 11 inches. Planning 3 coats of EG.



I had to razor trim the frog tape on the spray rail. It did not want to follow the curve.



Next up I wrapped shrink wrap from top edge to the bottom over lapping it to keep any drip off my primer.
I used more frog tape from waterline to shrink wrap.



Best I could do. Holding the line over the spray rails is dang near impossible.



I used poly coated paper on the transom. I don't know why.




Before I start putting the graphite on the bottom I'm going to do a test board using different rollers to see what I think does best.
I have a 3/8" nap roller, a 1/4" nap roller and foam. I also want to see if tipping will bring anything to the picture.
I'll get this set up this afternoon.

[Jeff]

Eric, as usual, first class prep work!!! Jeff

[BB Sig]

Looking good! I'm looking forward to your test results.

[Jaysen]

Foam. No tip. You don't have much working time. Tipping will leave you with rough streaks.

I'd seriously consider more than three coats. While the graphite is hard it does take a beating. Especially in the impact/rub areas. When I get to the point of redoing Lil Bit I'm going to shoot for at least 6. I'm hoping that will last a bit longer.

That looks like some awesome prep. You will appreciate that.
