This brings me up to date.
Yesterday I applied the semi-gloss acrylic to the cabinet. 50:50 mix of paint to thinners.
I applied two lighter coats, covering up all the undercoat and then very lightly sanded with 1500 grit. Surface air blown and felt really smooth.
Another coat all over paying particular attention to edges and corners not covered by decals.
As I posted yesterday the final result left small pimples on the surface. Now these were fine and minor with some areas feeling slight abrasive.
After advice, and still having a small amount of paint remaining, I very lightly sanded with 1500 grit, air blown and wiped with a clean rag. Surface was really smooth. I thinned the paint to maybe 40:60, ie more thinners, and applied a final coat.
Well I think I'm there, surface feels really good, and looks well.......better around the edges where it will be visible.
Decals to come soon!
