Anyone think that the T70 C 60 nitro lacquer from sherwin williams would be compatible with Behlen Nitro that comes from Stew Mac? I need a few more coats of lacquer on this guitar and I'm trying to find some nitro from a local store. I know that optimally I should obviously use the same product, but in theory should it work to mix products just so long as they are both nitro?

Maybe it wouldn't matter, but I never did it.
I made enough mistakes just trying to follow the usual rules.

Haha. Seriously. I am spraying outside and I keep running into disaster after disaster. Overall it's looking fabulous, but I keep having to razor blade out little bits of pollen that blow in the wind along with the occasional bug. dang things. It is very pleasant to spray outdoors though.

Does anyone know of any other nitrocellulose lacquers that are readily available at paint stores or hardware stores?

This is what I've got going on.



It's pretty flat now. I have enough lacquer for 3 good coats over the color. I might be able to get away with it. Or maybe I need a couple more layers.

Ah, yes - spraying outside simply ups the chances of trouble compromising the quality of the finish, or the ease of applying it.

I have done it. But only when absolutely all other avenues were exhausted.
You just can't control the outdoors.

I've used Deft spray lacquer from Home Depot and Lowes. It seems to be OK.
Do not use Minwax lacquer - it's an acrylic based "lacquer" and will never get hard and is not compatible with nitro.

Yeah I hear some saying that Minwax among other hardware store lacquers are indeed nitro but I find this unconvincing. It seems to me that if it were nitrocellulose it would be clearly marked on the can as being so. But perhaps they are. I may well just order some more Behlins to do it correctly. Actually, I started with Cardinal, from LMI, and now I'm on Behlins. haha I feel pretty good about meshing those two though.

I am now just exhaustively searching the web for finishing options while deciding how to move forward in the future. I have just found this one interesting nitro, and it is inexpensive. Anyone ever used Gemini Precatalyzed Gloss Lacquer?

There's not alot in the way of Nitrocellulose options out there that I find, but one I keep coming across is made by a company called Old Masters. Anyone got any info or experience with that one? It is clearly labeled as nitro, so that's a good start.

Most readily available lacquers are acrylics. To your initial question, can the two brands be mixed? No one knows. You will need to try it and see, could ruin the finish. Could be fine. If you have a Woodcraft nearby, they generally carry Behlins.

Go on the web and seach for the product safety data sheet.
The manufacturer is required to list the ingredients. Minwax is acrylic based.
You may be able to compare different lacquers for compatibility.

MSDS only really list out the hazardous materials like the solvents. Most solvent packs look very similar on paper and will probably interchange. The resins on the other hand are usually inert and not listed on the MSDS and they are the components that must link together to form a viable coating.
