Be careful w/sanding it's easy to sand thru any veneered surface and that can be a problem. I like chemical strippers to remove old finishes. Lacquer thinner and a rag work good if you can stand the odor. Or Citristrip is not bad used w/ some odor less mineral spirits for the final cleanup.

I don't have a dedicated room or out building to spray in either. I do it out doors. Just a couple of rules, 60/60 temp above 60deg and humidity below 60%,  windy days are not a good day to spray. Oh and if your neighbor is running a mower or leaf blower not so good either.

I don't think that Howard's is going do much to even out the light vs dark areas or where the toned lacquer is worn off. It's more of a add a little bit of darkness the shine to it kinda stuff but where there's that much contrast it falls short.
