Shellac and lacquer are both fairly easy to identify because they will redissolve in their original solvents. If alcohol (solvent alcohol from the hardware store, not rubbing alcohol) dissolves it then it's shellac. If lacquer thinner softens it, then it's lacquer. (lacquer thinner will also dissolve shellac, but alcohol will not immediately soften lacquer, so do the alcohol check first.) If neither alcohol nor lacquer thinner immediately affect it, then it's probably varnish.* http://ths.gardenweb.com/forums/load/wood/msg0822004022412.html
To a degree, but if you are concerned use lacquer thinner.
Lacquer thinner has no sheen. It will thin any lacquer or enamel and imparts no gloss or change of that nature.
The solvent for varnish is lacquer thinner, but I cannot speak to what the lacquer thinner might do to the woolen item.
Yes, you can use a lacquer thinner on carbon fiber. However, when doing so, make sure you water the thinner down first or add it to a solvent.
Lacquer thinner evaporates quicker. It is cleaner or leaves less of a film than paint thinner. Lacquer thinner will thin most solvent based paint but paint thinner shouldn't be used to thin Lacquer. Lacquer dries from the surface painted out and enammal dries from the surface of the paint down to the surface painted. Using the wrong thinner affects how the paint dries and may affect the final finish.
Lacquer thinner will possibly remove it, chemical stripper will definitely remove it.
Lacquer thinner.
Lacquer thinner will thin many types of oil based paint, but not all. -Experiment with a little first.
yes, mixture of 1/2 clear lacquer and 1/2 lacquer thinner. You can also use polyurethene spray
It may or may not be effective. Traditional lacquer is a nitrocellulose-based coating. Thinners for nitrocellulose include acetone and ethanol (drinking alcohol). Most nail polishes are nitrocellulose lacquers, and that's why acetone is used as a nail polish remover.In general, the rule for thinners is that you need to use the thinner that was originally used to make the coating, or which is sold to be a thinner for the coating. If what's on your brushes isn't lacquer, lacquer thinner may not work as well as a thinner designed for the coating, and it may not work at all.If you already have lacquer thinner somewhere, or some nail polish remover, why not try a little bit to see if it works?
Varsol, oil thinner, turps, lacquer thinner, xylene, and many others.
