Polishing with some oil tends to be faster, as it extends each polishing session (although not by as much as you might think), but I find I get better, more consistent results if I don't use oil until the final stage.Echi wrote:I bought the DVD as well and found it very good and professionally made. Highly suggested.
Later on James wrote on Delcamp to have changed his method to apply shellach as he now made use of few oil if not all. I'm curious to know what is the fastest and more consistent of the 2 methods?
Not a bad idea, but I'm not sure I could face making another DVD. If I'd known how much work it would be before I started, it would probably never have happened.Brian McCombs wrote:......and I have a suggestion for James:

Just adding more polish in that one area isn't a good idea - you could easily make it worse. Any of the other suggestions are possibilities, but probably the best is to sand back very lightly, then just carry on building up the polish on the whole rib as normal, but just spending very slightly longer on the damaged patch. The waist area is usually the highest risk in terms of dragging/digging in. A smaller pad helps, but really you just need to take a lot of care there.Brian McCombs wrote: For instance.... While polishing out my side, near the waist my pad may have softened the surface too much and it "dug in" a little bit....like it tore into the surface leaving a nickel sized smudge. Do I try to sand it flat? Do I add more polish just in that area, attempting to fill it in or build it back up and then sand? Then re-polish? Should I Just try alcohol and oil and try to flatten it or polish it away? I'm not sure how to fix it.
Again the head is tricky because it's such a small area. It's not a bad idea to add a bit of polish to the head at regular intervals while you're polishing the rest of the guitar, rather than do it all in one go.Brian McCombs wrote: and.....my headstock is streaky, parts of it polished out ok, but there are bands or streaks....I don't know if I disturbed the flatness of the surface and caused it...or is it too thin, I didn't get the build I needed to begin with so it is dull, nearly burned through? Do I just build some additional layers and the sand back lightly then perform the polishing task over again?
Unless your pad was too wet, you won't have left much shellac on the good surface, and it should be easy to blend it in with subsequent sessions on the back - if not, a little light sanding will remove it.Brian McCombs wrote: and.....While polishing the side my pad slipped over the edge and skipped across part of the finished back....I was drinking some beers and couldn't keep it between the lines....I guess. It made a mark in the polish, the mark I think is just a little shellac deposited on the glossy surface....do I try to burnish it away with compound later, do I lightly sand the area and then re-polish or do I use alcohol-oil mixture to try and flatten it out? Whatever I choose to do I risk messing up the surrounding areas.
Good advice...Paul Micheletti wrote:I've learned that when you mess something up, you need to expand to a much bigger area for the repair. If you focus on a small area during french polish, you will inevitably burn through that area and have to start over in the build stage.
(I use the piece of carpet the guitar rests on during polishing.)Paul Micheletti wrote:Just keep wiping the micromesh on your jeans or on a towel as frequently as possible so it does not load with shellac and cause a bigger problem.
