Hello All,

First of all, a general thank you---you guys have been most helpful, and quick to respond, and I really appreciate it! I know so little about repairs that I can't even fix my own mistakes (;->)...

In my rush to meet a deadline---never again!---I got too agressive scraping down some back binding, and opened up some filled pores in an East Indian rosewood back. I've been attempting to fill them with thin CA, under the assumption that the thicker varities won't go down into the pores. But in spite of putting on a generous amount, the thin stuff either soakes into the wood or shrinks (?)  I have both the medium and thick CA. Should I be using one of those?

Cheers,

Brian

Hi Brian, when I've used CA for pore filling, I always used the medium or thick stuff. I worked it into the pores with a credit card. Worked fine for me.

Thanks Glen,

In my dozen year search for a clear pore filler---and trying at least as many products---I found that the thicker viscosity fillers would skin over the pores, and I would open them up again when I sanded back to the wood. I'll give your method a try, and start with the medium stuff. 

That's really the best use for a credit card, isn't it (;->)...

Cheers,

Brian

For me, I don't sand back to wood after pore-fill.  Maybe this is why I haven't noticed a problem (yet).  I do blow out the pores with my air compressor (make sure I don't have any dust in the holes) and work it down good with the card.

I, like yourself, searched long and hard for a clear pore-fill (that was my goal with CA). I tried all the water bornes and all but settled on System 3 epoxy resin.  The CA was the best I found, but it ate my eyeballs out. Yep, I tried the googles, fans, etc and just couldn't handle it.  Since I only had two, I settled for the epoxy resin.  

I've heard the polyester finishes pore fill great, but I haven't tried them yet. $$

Another thing I've done is modified my expectations.  I have just come to accept that some shrinkage may  occur and well, if it does 'so what?'.  I look at high end Martins, Collings, Taylors and have seen some pores show on them also.  I usually keep all my builds for a couple years and if shrinkage happens, sometimes I level sand the nitro and re-buff if it really bugs me.

Hello again Glen,

I finally settled on plain old shellac, with all its problems. Now I don't sand back to the wood either. I just apply shellac until the pores are really filled, and have had enough time to shrink. Then I use Assilex and Buflex ---eagleabrasives.com---to bring up a moderate gloss. Classical guitarists are Fussy! So I try to get as complete a pore fill as I can.

Cheers,

Brian
