I’m pleased you found my ‘article’ interesting Mark especially if it helps motivate you into restoring your Vega.

If I was in your position I would carefully remove the veneer from the whole wing, however if some of the veneer is still so well bonded that it won’t come off easily leave it as you must not damage the surface of the foam core. Obechi veneer is not easy to find but I noticed some on Ebay yesterday, 10 off 36” x 6” packs plus instructions on its use for £12.50 inc P&P which seems a good price. I use Copydex used as a contact adhesive to stick down my veneer, this works well but is quite expensive.

I would always cover the wing with glass on a high aspect ratio wing as it gives a lot of extra strength at the expense of a bit of weight gain. To bond the glass you can either use epoxy resin or one of the new water based adhesives.

There are two water based adhesives that I know of Poly C and Skincrylic (from Falcon Aviation http://www.falcon-aviation.com). Do a search for Poly C on this board as Greyhead started a tutorial thread a while back that is quite informative.

As to which to use on your Vega? If you can remove all of the old veneer and totally recover the wing with a good bond then I would go for one of the water based products as they are nicer to use, but if you can only partly re-veneer then I would use epoxy resin as my gut feeling is that it gives more strength to the wing plus there is no chance of the water base causing areas of veneer to lift where they are not fully bonded.

If using epoxy resin apply the resin with a roller not a brush and use many thin coats as thick coats can cause disappointing results, rollers and materials are available from Fibretech http://www.fibretechgb.co.uk.

I bought a ‘started’ Pat Teakle HP-18 recently, unfortunately some not so careful previous owner has rather butchered one wing so I will need to glass it and I will write it up for this forum but it won’t be for a while yet I’m afraid. I had a word with the Falcon Aviation rep at the Teeside MFC Show and he said to lay the glass over the wing and but a heavy(ish) strip of adhesive down the length of the wing then brush this out towards the leading and trailing edges. If either the leading or trailing edges are straight then you can use one piece of glass cloth, do one side leave it until it is almost dry then turn the wing over and quickly do the other side.

Hope this helps.
