how long after the last coat of lacquer should I wait until sanding and polishing?:?:
I wait 3-12 weeks. If it feels sticky it is sticky. The reranch I used was hard as a rock after 2 months. The deft I used still feels a little tacky after 6 months.
If using spray cans I think the general recommendation is 30 days. If mixing and spraying with a gun I see guys getting good results in a week. I know with cars we would do a rough sand after a week or 2 and then a final sand and polish at about 6 months. This was for cars we showed.
I've used McFadden and Deft products thinned and sprayed with gun sprayers.
I usually sand and buff after 2 or 3 weeks and haven't had any problems. The finishes seem to be plenty hard enough to work up nicely.
Easiest way to tell is the "fingernail test." If you can dent the lacquer by lightly pressing it with your fingernail in an unobtrusive area, such as the neck pocket or a pickup cavity, it's not ready for polishing.
30 days cure time is usually OK if you haven't layed on a lot of clear coats.
Similar experience. 6 weeks and I finished the reranch to a super high gloss and was rock hard, using Watco I couldn't get the same shine but after 5 months took it apart and did it again (once it was really hard) and it's perfect.
The reranch one was hard enough to assemble after 2-3 weeks but wasn't "ready" to be brought up to a finish.
I agree; I assemble once about two months' in. Play it in. Take it apart a few months later and polish it up if that seems to suit the look of the guitar, some are actually OK as they are. I think.
I used Mohawk Instrument Lacquer, left it in a small powder room with a heater set to about 75* and after two weeks I could'nt dent it with my nails. Works great if you cant wait longer.
