Are you trying to spray a car, a boat, furniture?
Metal, wood, the list goes on......
Need more info before we can give a sensible answer (and even the that is debatable)

nitro's been obsolete for many years.
For all practical hands on purposes acrylic lacquer is the same thing.
Mirotone is a highly respected brand.
Wattyl do make one but you can only get it from a wattyl trade centre etc and not from hardware stores.

I am using Mirotones furniture lacquer, its great to work with, dries very fast.
Usually thin to about 30-40% with lacquer thinner.
I use HVLP spray guns for less over spray
Australian suppliers

Bob what is the difference Chemically and practically. The lacquers I was shown in the car paint shop todat seemed to be Cyno Acrelates & hydrocarbons in a 2 pac (not the rapper coz he ripe) form.
Are Acrylic Lacquers a 2 pac thing or what? Do subsequent coats melt into the previous? Cant it be buffed?

OK, nitrocellulose lacquers are still around and being used every day. The manufacturers mentioned above, eg Wattyl, Mirotone etc make them. Just ask for pre-cat lacquer and they will do what you want to do.
The MSDS for the Haymes version can be found here, Protec also make one and various other manufacturers. A supplier that specialises in automotive finishes is not the best place to go, they were right in effect, N/C lacquers are old hat in the automotive scene. Another finish you can look at is automotive clear coat (ie the final coat that goes over the pigmented coats). They are usually 2 pack urethanes, but are much harder to apply and handle than pre-cat lacquers.
Edit: Btw this question has been asked before, if you do a search you will find a very comprehensive answer from Durwood.

Thanks Big Shed are Pre Cat Lacquers as they sound a single pac product?
What sort of drying times are involved and how dust tollerant is this finish.

G'day Ross, yes they are a single pack product, pre cat stands for pre catalysed. They are available in several gloss levels. Being N/C lacquers they dry very fast, so dust should be less of a problem than, say with a single pack urethane.
The drawback with N/C lacquers is that they are not suitable for exterior work or for more heavy duty applications such as bench tops or bar tops (low alcohol resistance).
Perfectly suitable for your guitar or coffee table etc. You will find that nearly all furniture is sprayed with this type of product.
For bench and bar tops you should be looking at either a single pack moisture cured urethane, a two pack urethane (Wattyl 7008) or the 2 pack acrylic urethane clear coats used for automotive applications.

Pre cat is not NC but is the same to use, Its more durable than NC. Still not suitable for exterior use though.
It dries in 10 to 15 seconds or so.
Be very wary of 2 pac furniture finishes, you need to read and understand the msds properly. They are very severe risks with some of them. I recall 1 product which stated full breathing and body suit was required and do not use their products if you were not prepared to do that.

Different, you may be interested in Bob Flexner's book on wood finishing, available for free down load here.

The password is displayed on that download page, it is www.freebookspot.com
The file itself is in djvu format, so you will need a reader for that, I have downloaded stduviewer.exe from download.com, but Google throws up others, both free and shareware, as well.
