I'm putting the finish on my first, as many of you may already know since I keep asking finishing questions

.
The back,sides and neck are mahogany which I porefilled and stained. I was planning on using a few seal coats of shellac then finishing with truoil. The stain was alcohol based and I'm pretty sure when I *rubbed* on a seal coat of shellac over my stained neck some of the stain got smeared a little. Does that sound probable? Maybe it was streaky before I just didn't notice it
So I was thinking about just putting the Tru Oil directly on the stained back and sides. This shouldn't cause a problem should it? I still plan on sealing the top(spruce) with shellac then finishing it with Tru-Oil.
Any advice? Can anyone confirm that rubbing shellac (dissolved in alcohol) over an alcohol based stain will smear it? What are your thoughts on the Truoil affecting the tone by being applied directly on the wood of the back & sides?
