Post subject:  Stripping Conversion Varnish

I'm a full-time luthier/guitar tech,with years of experience using nitrocellulose laquer,but NONE with conversion varnish.A customer just brought me a Jetglo 4003 bass,with the finish on the back of the neck badly damaged.I talked him out of re-finishing the whole thing (whew!),but he wants the back of the neck stripped to bare wood.I suggested sealing it with a satin finish nitrocellulose laquer,to keep out the grime/sweat/oil/etc...,and he is cool with that.I've touched up minor dings on my Jetglo 325 with black N.C.laquer,& was happy with the results.My question is:what stripper will work best with C.V.? I've been using 3M Safest Stripper on N.C.laquer,and it works great.It's non-toxic,doesn't smell bad,gentle & slow.It WILL,however,melt ABS & Celluloid binding,so I'll have to double mask it with heavy brown Kraft tape.Will it work on C.V.,or should I use BIX,Zip Strip,or something stronger?If Jingle Jangle or Dale Fortune could help me with this one,I'd certainly appreciate their input.Anyone out there with a clue?

I'd recommend that you go with what you thought originally, and that's to talk with Dale F. and /or Paul W. They're the ones who know conversion varnish.

Beatlefreak,I think that you hit the nail squarely on the head...I'll email Dale & Paul tomorrow.Paul's recent 360 restoration/re-fin to Azureglo was STUNNING,& would match my Azureglo '82 4003 perfectly...thanks for your prompt input...

I'd avoid nitro as a sealer. So many luthiers know nothing but nitro, I think they have stock in nitro companies. I have had problems using nitro under CV--checking and long-lasting softening of the nitro under the cured CV topcoat; sensitivity to heat causing softening of the nitro undercoats.

RIC uses reduced CV as a sealer, as it is 100% compatible with the CV finish coats. Use it. It'll give you experience in the chacteristics and application of this material, which is not for the faint-hearted at first.

ANY stripper that I'm aware of will dissolve the binding material. I use good quality 3M tape and renew it with each application of stripper. Tape 1/4" minimum inside the binding, and use two or three layers. Then, after the stripper has been scraped and steel-wooled off and the bass has dried overnight, take off the tape and sand away the remaining CV and paint.

Ken is right. I also prefer Jasco Premium (gold can). Hot stuff.
