jamesmulholland -> FP touchup...meltdown over stubborn spots (Aug. 21 2026 21:48:51)

Hi all,

After trying for weeks to get two infuriatingly stubborn spots to take polish, I gave up and sanded the area completely back.

Am I now realistically looking at going all the way, sanding the whole top down? Or can I just repolish the target area?

Thanks for any tips.

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...!

Cheers,

James
