Shellac finishing problem PLEASE HELP
Hi
I am currently finishing a guitar with hardened white shellac. I have then buffed it with a polishing compound. Everything was going fine until I stupidly buffed through the finish in one spot.Taking my medicine for the stupidity, I have taken the area back to bare timber to re-apply the shellac. I now find that the shellac will not take to this area. Can anyone suggest a solution to this problem, please?
Thanks Tony

It think it "polak" is a polishing and waxing compound. It is sold around the world under various names. It maybe even rebadged porzelack.
Think you guys are right ... contains silicon ... it may also contain teflon ....

Removing silicone? best of luck, you'd need a heavy duty solvent....even then
FYI.....EEE Ultrashine is the suitable cut and polish compound for Hard Shellac, works beautifully........

I had a bit of a search on the net and the best advice seems to be that whatever solvent you try throw the rags etc away after one sweep otherwise you keep recontaminating.
good luck,
Jim

Car spray painters use PrepSol. Designed to remove waxes etc before re-spraying.

Thanks to all for your advice. It is much appreciated.
I again stripped back the shellac from the area and thoroughly cleaned it with alcohol. At first I had similar problems, but gradually I was able to build a reasonable amount of shellac over the area. After later rubbing back I now have a smooth surface that the shellac is covering as well as the rest of the surface. The damaged area is a little lighter in colour, but that doesnt worry me too much. If I am not happy with the final result, I will take it all back and try your suggestions.
Thanks
Tony
