Graphite is what I use. It is also what professional plug builders use and it is used by many auto body shops.

You may wonder why some of my tutorials show spray paint? Simple, we were out of graphite those days and spray paint is a good substitute.

Another good guide coat is alcohol or water with ink. There is a special ink used by pattern makers: Dykem.
Food color sounds like a good idea too but try graphite, it is very fine, show every scratch, no liquid and it is 100% compatible with epoxy.

Thank You Everyone for the help!

Tom here is the paint I bought. The "dries in 15 minutes" is what got my attention. It can't be the right stuff.

Image

Here is why I say that. This is after 2 days of cure time. One minute of sanding and my paper looks like this. :x
I'll wait on the 3M stuff to come monday. I'd never use this paint again for this purpose.

Image

So I finished the Quick Fair application from Chine to Trim line. I changed the way I was putting it on. I found it easier to apply it to the surface just under the spray rail first. Then I applied it above the trim line. The bow took a good bit more to fill. There are multiple overlaps of biax just under the spray rail area. I'm pretty happy with where I am.

Time to take the girls out for lunch!!
A Happy Weekend to you all!

Boat is looking very nice there Eric. Even with the guide coat headaches you are getting there.

Hey,

It´s looking very good!

I used the spray paint after I saw you doing!

It helped a lot, but the fairing drank some paint and the points where the fairing board just touch it stayed colored.

Regards,

Carlos Sotelo

I was able to get a few hours in after lunch today. I hope I'm not boring y'all with sanding pictures but that's all I'm doing now. Fill,sand,repeat. Anyway I got the first eight feet on the side sanded with 80 grit paper. I'm glad I decided to fill and fair this again. Between the Quick Fair and the blue paint I can clearly see the lows.

Close up:

Image

I also sanded the entire bottom half down with 120 grit. I still have work to do here also.

Bow lows reflecting light.

The guide coat powder came in today but I did not get to use it yet.

I thought I posted this yesterday but I guess I forgot to submit it.
I spent all of yesterday sanding, First caught up this side panel with 80 grit, then sanded the whole panel with 120 grit.
I was wore out.

Image

Then my brother wanted to show me the way he would fill so I cut him loose!
He seems to think I'm putting it on a bit thin, I don't know. This was another 30 grams.

Image

First thing today I sanded the second fill out. It looks pretty good. I'm going to spend time with a bright light and do fill work today.

Image

I'm going to start with this corner transition, Tired of looking at it. I built a dam from G10 and peel ply and got it in place.
I plan to round this but I think this is the easiest way to fill it.
