RE: FP touchup...meltdown over stubb... (in reply to jamesmulholland)
I've found that such areas can be induced to accept polish by first applying some shellac by brush--not by brushing it on, necessarily, but often by dabbing it on by touching with the tip of a small brush that is not holding too much solution. The touched-on spots have to be separated from one another, otherwise they run together and make a mess. It may look funny at first, but after subsequent drying and then polishing, it looks right.
In your case, since you've sanded the areas back, you could actually brush on seal coats in the areas and then polish. I would try that before anything else, since there's little to lose.

Thanks very much Ethan. I should've posted before losing it...
I ried several times dabbing on more shellack - with initial promise, but the end result after light sanding and polishing was always the same. I thought maybe it was due to oil, but lighter fluid, even acetone treatment didn't help either.
I will give the separate dabs idea a go next time. Perhaps in a week or so, when the same spot shows up again after reapplying...!
RE: FP touchup...meltdown over stubb... (in reply to jamesmulholland)
I'm not sure if I should start another thread for this, but will try posting here first.
I haven't finished repolishing yet, but have encountered this hideous reflective/refractive problem with the area I sanded back. Plus a horrible lighter area on the feathered edge, which I can't seem to blend.
When the light source is the same side as the viewer, the fresh FP seems definitely darker than the original. It's the same viewing from the head as it is from the bottom.
With the light is on the opposite side, the fresh patch seems lighter.
And from the side, it's uniform (except for that damn feathered part)
Could this be down to a different grit of sandpaper, abrading/squashing the spruce fibres differently?
The shellac mix is a 0.5lb cut, which I'm pretty confident is what I used on the original.
Thanks again for any insight you may have. And sorry for the massive image size...
