Problem is, the OP cannot add that to his rattle can. He hasn't said whether he has a spray rig.
Then spray on a dry day, or run a dehumidifier over night to bring down the humidity.

Its only an issue during the application process right? I dont know for sure, but I didnt think a finish would absorb after its applied, rather this is the result of trapping during. Similar to heat, finish flows better at ~70* but once it is on and “settled” or dry to tack, it’ll cure just fine in colder weather, as I usually open my garage doors after application to vent fumes (wearing a respirator during application of course!!)

I did take some lacquer thinner to it and it did clean up the white I am going to let it set to make sure nothing comes back and then top coat it with either more lacquer or maybe even some shellac or urethane? Not sure what would be the best top coat at this time.

It was sanded and then just sprayed with Watco Crystal Clear Lacquer (spray can) which I have done a few times now with no problems. I like using this product as it dries fast and you can put multiple coats on in no time.

Well this time it did not turn out, the project started to get a white film in the finish big time. I was spraying in my shop which was about 78 degrees (wood burner Michigan) I also put a new coat on about every 30 minutes. I did put a lot of coats on but that should not make a difference (I believe) any Ideas on what went wrong and how to correct the problem. Sanding off the old lacquer would be difficult as some of the project is 3-dementional.

Thanks Richard

I'm no expert, (but the Corvair buffed up like a million dollars); I'd say "retarder".

Retarder is the key...High humidity can cause lacquer to "blush" if it dries too quickly...
