cork sniffers resonator project

[nitroburner1000]

Some decisions made and a little more movement, leading to yet another question.
Sides and neck Painted black (oil based enamel) 1,500 grit wet sanded back, now smooth but dull finish.
Do I spray poly over smooth dull black finish hoping for a nice deep black shine result?
Or do I apply another shiny coat of black then without sanding apply the poly?
The back will also be painted before poly (colour TBA).

Never spray or paint any gloss finish without sanding dull inbetween coats as the new layer will have nothing to grip to and will eventually delaminate. If the black has had enough coats and is nice and solid then yes spray poly straight on but ALWAYS DO SAMPLE TESTS FIRST on scraps if possible not the guitar.

Thanks for that advice.
The job can now move forward :-)
Actually it's been taking two steps forward and one backward etc for the last few days. I've had an "Oh sh*t" but correcting measures are in hand. I'll post about such this week once it's all under control.
