Great stuff.

Thanks Dave. I will see if it is available here in Australia.

Jim.

edit: What size tip are you spraying that through Dave? I have found a source here in Aus.

Jim,

Im using a Binks HVLP Touch up gun. Depending on how thin you make it, I can use the standard tip for finish coats or my second tip is a 30 T according to the box for thicker sprays.
You can thin with either MEK or Acetone. I prefer Acetone as I have a bowl next to me for quick cleanup anyway.

What I do on a fresh glassed plug after it has gone off and ready to coat is, mix a small batch and paint it on the surface in a area about 6" long and squeegee it into the weave. Continue this until the whole surface is done. This fills all the pin air. When it has tacked up go ahead and brush, spray or roll your first sanding coat.

This is a polyester based material and you have to use catalyst as a hardener.
Don't get it too thick, like making fillets as it will shrink and crack.
I use Bondo for thickness and finish with Duratec.

Any questions while your using it let me know.

Tuesday I prepped the Ghost mold with epoxy and milled fibers around all the edges. Then mixed my surface coat. Something wasn't right and sure enough I botched the mixture and it did not go off correctly. Ended up striping it off by laying up a layer of glass over it and peeled it up.
So now Im refinishing the wing surface and will continue the thread in a few days after I fix my mistake. #%$@ happens.

Dave

Thanks for the details Dave. Meanwhile our local suppliers suggest a gun with a 2.5mm tip. The price of 1 gallon here is around $180 plus delivery. That would put it up to around $220 which is a bit prohibitive, especially if I add the cost of the special gun.

Undecided,

Jim.

Jim,

It is expensive, just over $25.00 a quart here. I would not buy a gallon just because you will never use that much before it goes off.
I used just over a quart to do the P5 and all the parting trays. Also you can spray it with a regular gun. No need for specialized equipment.

And yes, there really is a shortage of elbow grease users.

I thought so too Dave, but the supplier here only does it in quarts. I will try and find smaller quantities elsewhere.
It sure sounds the way to go!

After I botched the surface coat I have cleaned everything up and did a polish on the wing to check for any waves or irregularities before putting it back in the tray. Looks pretty good, I will continue next week with starting the glass layup.

Oh yeah...looking great.

Are you using a polishing machine, like a buffer or something?

Yep, Surfboard tech all the way. I use a power sander with a polishing pad. The plug is taped down so it wont move. I use a cutting compound and liquid polish. Its really dangerous for the plug as you can hook an edge and total it.
Defiantly risky unless you have some experience.
