Acoustic Guitar Construction

I am using Qualasol. For the most part it is going ok.
But I have some dull spots on the back which don't seem to want to shine like the resr of it.
No matter how many coats I am putting on. Can somebody tell me how I can fix please.
Here is a pic.

Thanks,

What did you do to prep the back before starting the FP? How are you applying the qualasol?

Well....I pore filled the entire back with colortone grain filler from Stewmac (water based). Then sanded it smooth.
I applied Salasol with cotton balls wrapped in a piece of tee shirt, with little olive oil. For the most part I got a good shine, except for a some stubborn dull spots.

Looks like perhaps I am gaining on it. I decided just to dap the qualasol (instead of rubbing).
Seems like it sticking now. Here is what I got now.

Yes looking better.

With qualasol you can leave out the oil. Instead of dabbing or rubbing try and apply it with a folded line free cotton rag in long strokes with the grain. The streaks should be wet but not so much that you would get a drip. Let any streak dry to the touch before hitting it again. Do this until you get an even base coat. Qualasol lends itself to padding as I described above without the need for a FP technique. I think you were pulling off as much as you were putting on in the dull areas.

Thanks for the tip.
Getting lots of practice for the top.

One more tip. I do not use oil with shellac until I have a good base coat. Three or so applications with a pad. Basically you do not want oil on the bare wood.
