Nice looking guitar coming along there
Danish Oil and Tru-oil are similar in that they are polymers with natural oils like tung and linseed. They can literally be wiped on with a cloth then left to sink into the wood and harden after a few hours. By building up lots of thin layers over a week you can get a really nice natural sheen, or buff to a good gloss. Danish oil is available in B&Q, Homebase, etc. Rustins Danish Oil is really excellent stuff, as is Watco and Colron.
Tru-oil is harder to get, you can buy on ebay or websites dealing with shooting accessories, its used to treat gunstocks. I think it hardens faster than danish oil but both will work well on guitar wood: bodies and necks.
Oh, you can finish off with 0000 grade wire wool and some natural furniture polish applied with a soft cloth. once applied, no re-oiling is necessary if the wood has had a lot of good coats. Buff up with a little polish once every now and then.
