Dale: Is it your opinion (and others welcome!) that DAG or other purported friction-reducing finishes on bridge tops are simply traditional? Is there a real argument against them? For them? Your (and others') natural bridge tops are quite lovely, I have to say, and I am tempted. Paul In a message dated 3/20/2009 10:05:56 P.M.

I think they call it CPES. I posted about last week. Was using shellac previously sprayed on sanded out & steel wooled & buffed. With this I simply brush it on several times let dry over night & it looks very similar to the shellac only it penetrates farther & it is harder. Interestingly it doesn't' mess with my bridge pin fit even applied liberally which means it is penetrating. It's a time saver & a better harder outcome. No sanding, no notch painting later. Looks good. I'll repost the picture. Dale Even though I don't put as much "back" into the finishing, I love to work with the board, before and after it's in, trimming it out and getting it ready for the next major belly steps. It represents a major achievement in the craft we pursue, and although I do use Andre's and don't make my own boards (at least not yet, with space and time issues), handling, fitting, treating, and finally seeing the expanse of finely shaped wood in place is still breath-taking to me. After 22 years of soundboard installation. Still a wonder. Bridge work is right up there, too! I'm considering going to the untreated top surface. Have been using the traditional DAG for years. What do you do on the tops for finish? Paul In a message dated 3/20/2009 6:59:23 P.M.

It appears that Stwy used amber shellac on all their old pre 1950s boards. Why brush on? I spray on one good wet coat as a sealer coat. Let dry over night & then Scuff it, then spray on 2 good coats of sealer, sand it out & then 2 good wet coats of gloss lacquer. Wet sand with 400,600, Then water wet steel wool on an flat automotive rub out hand tool which hold sandpaper & steel wool beautifully. Nice straight lines. It has a handle. Hand polish with Maguire swirl remover & a t-shirt cloth folded with no seams or creases It's a pretty nice look. On the bottom I don't rub out. Let it shine Dale Actually, here is a pic of a recent soundboard installation (bridges not yet sealed)...Mason AA...if you look closely, you can see the satin sheen result, and the color is just the way I like it, too.
