I usually finish in True Oil, a finish that I very much like. I have virtually no experience with nitro cellulose.
Last Summer I used my DIY compressor and gun to spray a whole instrument in nitro cellulose. I built up the coats (thinly) and then after a few weeks used wet/dry etc to get the mirror finish I sought.
Over the Winter several cracks have appeared in the finish on the cedar soundboard (along the grain). What's the best way to rectify this? Can I simply spray over with a thin mix and expect the cracks to fuse together? Is this perhaps a sign that the finish was too thick and it's therefore necessary to sand back before applying further lacquer?
The rest of the instrument is fine, but is this a sign that further cracks may appear in the future?
