Post subject: | French Polish Problem |
I'm working on a guitar that I'm french polishing. Today, for the first time, I noticed tiny, tiny white specks in the finish of the cedar top. There are no such specks on the cocobolo back or sides. At first I thought that the cotton rag I have been using had shed, but since there are no specks on the back or sides I think that's ruled out. Any ideas? It's been in the mid 80s with the RH in the mid 30s so I don't believe the problem is humidity related. |

Are the white specs In the finish or in the cedar? If in the cedar it is probably mineral deposits. If in the finish then some kind of contamination > filter your shellac. |
