DTL-1 Ash body. First build

[Johnny Bravo]

Hi all - really sorry for asking a question that I know has been dealt with time and time again, but I've been back through the forum threads and I'm still a little lost.

I have the maple neck and the maple fretboard and want to use an oil (with W&D sanding as appropriate)

I had decided to go down the path of Boiled Linseed Oil and had proposed to use that front and back. I'm using this video as my source: https://www.youtube.com/watch?v=rlkfUoWLH_o

But is Tru Oil better?

Also, if I do go down the path of BLO (and it's ok to do front and back), I'm comfortable with the approach in the video above but would I also do some light W&D sanding on the fretboard, too?

Finally, what's a "reasonable" number of coats - factoring in that drying time at the moment is pretty good/I am a numpty?

Thanks in anticipation, JB
