I've been trying out Taffy's idea of filling goggles with cyano glue after painting the eye detail I'm getting there, several thin layers are in order.
Peter, you may also want to try 2 part 5 min. epoxy for the goggle lens........it dries clear and smooth, has a semi to gloss finish, and if you support the helmet/goggles so that they face the ceiling while applying the epoxy, the epoxy will level itself within the goggle frames....a small drop or two will do, and in 5 mins. you will have a finished lens, that needs no further finish work. I have used this method on several drivers, and have been delighted with the results.
Yes Peter, a couple. Will find some pictures. I have a few pre war cars such as the K3, SSK etc too.Most not built by me but interesting I think, all the same.
For goggles I use the same idea as the cyano and 2 part epoxy but use a proprietry canopy glue from the R/C world. Probably just PVA but also sets hard, smooth and clear PLUS it has the advantage of coming away easily should it not look right.
