I want to finish some fittings for in my shop. They are made from MDF and have been sealed with shellac.
I was going to use a 2 - pack acrylic lacquer topcoat, but my supplier no longer carries this stuff. They have 2-pack polyurethane, but I am not sure if the shellac is compatible with it.
Does anyone have any experience that they would like to pass on ?
Thanks in advance.

I may have answered my own question.
I've got some 2-pack polyurethane left over from another job. I mixed up a small batch and brushed some on the back of one of the panels.
It looks OK so far ( after 1 hour ), the paint is still a bit soft. But seems to have bonded OK.
I'll wait till its dry fully and see good it is.

Just came across your 2006 post and wondered if it worked.

FWIW I've done one pack poly - Estapol - over a couple of sad french polished coffee tables.
One worked fine; the other developed a whitish bloom of some kind under it after some years.

Sorry Guys, I have not actually sprayed these shop fittings yet, my test pieces still look good
I have everything ready, and cleared a spot in a spare shed, once the rain stops and the humidity drops, I will get them finished.
Also copping some flack about it from SWMBO :-.

Well the weather came good for me at the right time. I got the bits and pieces sprayed over 2 days.
The results look great. No trouble with the 2pack poly bonding to the shellac it seems.
Not sure if photos would help, but I will take a couple and see what they look like.
Charcoal coloured MDF shop fittings are nothing to get too excited about.
