There are so many variables, such as ambient temperature and humidity, formulation, etc. The rule of thumb I start by is two weeks, but generally I try to adopt the attitude that there's no short cut and that the longer you leave it, the better.Currently spraying 2 guitars in nitro and wondering how long I should let it dry before sanding. The info is all over the place, with other forums saying 4-6 weeks, and sites like StewMac saying 10-14 days.
Those of you who have significant experience with nitro, what's the ideal drying time?
It's not just curing either. Nitro gasses off for a long time and, after a month or so, you get shrinkage in coat thickness. You might notice this as the grain coming back through, especially if you skipped filler cos it was an Alder body and used nitro primer too.
If you're worried about rapid turnaround and it's your build, consider poly, 2K or even oiled finishes.
