Shellac

[DarkPenguin]

Is there an issue with putting down a shellac layer (like 4 coats) before putting down lacquer?  Just as a matter of course when you have something under it you really do not want to hose?  I think putting some physical distance to the lower layer seems like a good idea.  That and my paint doesn't react at all to shellac but seems to have issues with lacquer..

Shellac is pretty close to a universal interface barrier.  It's often used as a sealant between bare or dyed wood and a color or clear coat.  Whether you need four coats is probably more a matter of what you intend to put on top of it and how hard you sand between coats than a matter of actual need.  I tend to go with a little more shellac than I think looks right so I don't accidentally sand through.

I've used shellac as a sealer / base coat(s) on several instruments , it works well

It sure didn't stick to duplicolor.  Peeled off in sheets.

Was the shellac you used de-waxed? It needs to be if it's going to be used as a barrier between finishes.

I'm looking at using shellac to preserve a work of art by our own Great Ape.
We discussed using http://www.stewmac.com/Materials_and_Supplies/Finishing_Supplies/Finishes_and_Solvents/Zinsser_Clear_Aerosol_Shellac.html and he advised that this is what he uses.

I'm new to using shellac, and I especially want to do his fine work justice.
Any tips?

I use that same shellac to seal up my gold or silver leaf, save $10 a can and get it Home Depot though. Same stuff.

Thanks so much Rob!

Wipe on Poly after that, or is the shellac durable enough once cured?

Shellac isn't terribly water safe (put a coaster under the beer!) - but it's also inifinitely repairable with sufficient elbow grease after the fact. It's labor intensive though... I used it on my son's u-bass. I can't remember, but I think I went with a something else clear coat.

Follow up with wipe on poly it is then.
