I threw away all my Shellac and replaced it with Tru-Oil and Tru-Oil Wax for all my finishing needs. I don't especially care for painted guitars so 95% of my builds will be natural grain finishes unless I buy a painted body off Ebay. Tru-Oil is more time consuming than Shellac but if done correctly will give a nice hard finish. In many ways Tru-Oil is easier to apply than Shellac by virtue of just rubbing it on in a circular motion whereas Shellac is best applied with the grain. Also Tru-Oil doesn't dry while applying it and Shellac will get rather sticky as it is applied. Not only that Tru-Oil doesn't have a shelf life as strict as Shellac.
