Greg,PVA application by hand:- Use a small piece of rolled up "lint free" cloth, apply by wipeing very quickly a "thin" layer, and do not back track, as this will pick up the PVA layed down, the layer should be that thin that the PVA will "Appear" to dry as you watch it, however don't be fooled by this "appeareance", give it a good drying time, the worst senario is, if you apply the Gelcote while the PVA is still "wet" the Gelcote will take it onboard, that is, the PVA will disolve into the Gelcote.Pete Barsden

Bob,Mate the originals will remain as plugs and go into storage.I now have a mold for the instrument pod, just popped it half hr ago.Green Casting....now I'm gonna have to do some more study. Sonny is a bloody good bloke and has a lot of skills and knowledge AND he likes a drink.Pete,Good advice Mate. Yeah, I had the problem of the rag laying it down then pulling it back up again. Whilst I was out popping this latest mold, I hit the new face plate part up with some cutting compound which removed the PVA streak marks easily. Doing away with this step will make the process more efficient. Thanks for your help Pedro.Cheers,Mitch.Image Insert:

Well, turns out after I put my eyes on I could see quite clearly that the cloth had pressed right through the initial gel coat. It had been a cold day and seemed like the resin just was not going off. I should have had some heat control OR been more patient. So there will be a Mk 2 on the pod mold. I can do a better job next time and the part will only be as good as the mold it is made in. Mitch.www.thebutterflyllc.com

Here is the first black gel coat face plate sitting along side the first face plate made.This time I wiped the PVA on but still had to sand, then wet and dry and cut and polish the marks off.Also this plate had 4 layers of 200gram cloth with a descent thickness of gelcoat up front.Cheers,Mitch.Image Insert:

G'Day Gents,Talked at length to someone who knows a great deal about composites. Am going back to my original plugs, work them up again to do a 3rd face plate mold and 2nd instrument pod mold. Might sound like a bit of ginnin around but now I have times and ratios worked out and a little bit of practice and some top shelf advice, I should be able to roll out some product. Thanks Pete B.Cheers,Mitch.www.thebutterflyllc.com

G'Day Gents,I think you can see the face plate plug in middle is far better work up than original attempt. Both plugs have been reworked. Face plate plug essentially fully reshaped and as recommended by Pete B. getting painted and polished up. I have put in a lot of time on these plugs and hope it shows through to the parts.Cheers,Mitch.Image Insert:

G'Day Gents,Everything done up to the point was just messing about really. When Peter Barsden, ASRA Asst Technical Manager, offered his assistance. I gratefully accepted.Of course, this meant starting at the beginning, going back and doing it the right way.I even had to take a refresher course in how to paint.[:I][
)] I kept stuffing that up but here is the result of following the 'Teachers'advice.Instrument Face Plate Plug MkII mounted so as to be able to work it effectively. ie; pattern/plug shaping, sanding, painting, wet and dry to polish, waxing in preparation for laying up (laying on) the new mold. The new mold will also be pedestal mounted.So the big differences here now is no more mounting boards (which make it hard to work the piece down to its edges) and a vastly improved quality plug. Go back and have a look at the original unpainted plug and how the various surface materials are reflected in the mold.It is one thing to read a bunch of articles and have a go at something. But it's a whole new game when you have someone like our Asst Tech Mgr who steps in to help you 'lift your game'.Bravo Pedro, I very much appreciate all your help and advice.[
]I am looking forward to turning out a quality mold. I'll keep you posted. Mitch.Image Insert:
