Hi Alan,
welcome to the group. Age is no barrier, I'm over 60, I started building guitars a few years back as an alternate hobby to spending my life in front of and knuckle deep inside PC's. I was an IT specialist in a past life. I am the first to admit I can't help about the shape I'm in
I can't sing I ain't pretty and my legs are thin. The guys here have coated and coloured their kits in any number of different products.
They've used Wudtone, Dingotone, Shellac, Tung oil, Tru-oil, acryllic, Nitro-Cellulose, and even stuff out of spray cans. So there is a wide range of knowlege about what works and what doesn't.

Did you mean your kit was a SG1F, because if there is a 12F I want one... being a 12 string.

Cheers PK
