Any special prep before painting after glassing?

many thanks to 'all' who helped me with the fibre glass issue, you have helped a lot.

here is a photo of the sea commander front cabin rof having had "glass cloth" applied, the old bank card to spread the resin is in shot too!



the idea is to use the barest minimum of resin each time,

HI Dennis
Both will benefit from protection. The inside will also benefit from a coat of resin or at least dope. I mix a small amount of resin and pour into the hull, by tipping the hull at different angles you can coat all of the inside surfaces. This will take care of the inevitable water that will find its way inside the hull. Make sure you cover the underside of the deck, preferably before fitting.
I buy my glass and resin from a local supplier on a small industrial estate. Try your yellow pages / Thomsons local directory and ring to see if they will supply. You will have to buy in bulk (ÂA£30) as that is how they buy but the shelf life is long and it will cover models for a long time. Brushing on a final coat will produce a superb finish as dbninja suggested. Most full size gliders are finished in this stuff and it is really tough.
Good luck

I think you are referring to "glass-clothing" your wooden hull?

I can highly recommend this finishing technique for old wooden aerokits boats, and am doing all my restorations with it as it gives the hull a hard waterproof finish that is light weight and takes paint really well
you must use the correct resin and cloth available from good model shops...

the resin is called "Finishing resin" and is made by a company called Z-Poxy part number PT-40

if the model shop has the resin, they should have the correct glass-clothing cloth

the resin is around Ãa€sÂA£14 and the cloth about Ãa€sÂA£12, sounds expensive but there is enough of each to do several models so only works out at a couple of pounds per model

the best way to do it is cut a piece of cloth a bit oversize for each panel of the hull, lay it over the hull and squeegee the resin over it using and old credit card, you will only require really small mixes of resin to do the complete hull. when dry give it a good sanding and apply another coat of resin by the same method then sand again... you soon get the hang of it

pm me for more information if you want

HI Dennis
Depends on what you mean by wooden boats. if you are just intending to cover a previously made wooden hull then assuming you just need to protect the wood a very light coat of fiberglass and resin will suffice. For a small size (36") hull the extra coating will add quite a lot of weight and you will need to remove most of the resin with a roller/brush before it sets. Decks and cabins can be made from card, ply or plasticard and do not normally need coating with fiberglass. Card and wood benefit from a coat of sanding sealer (Cellulose Dope) to seal the surface prior to painting.
It would help if you could supply a little more info as to what you are building.
