West System or similar.

Commercial finishing processes rarely involve much manual work, if you use a self levelling primer after sealing you will have to sand rough areas after sealing but you won't need them perfectly smooth, experimentation will determine how smooth you need to go to achieve what you need ;-)

I've achieved good finishes on wood sealed with an alcohol based automotive sealer, U-Pol's version of this is Barcoat, others are available. Snother option if you want to do more sanding is to use a Polyester based spray filler, U-Pol's version of this is Reface, it sands very easily and doesn't clog paper like hand mixed polyester fillers,

You could try a shellac based sealer like Rustins Sanding Sealer. At least it dries quickly.

ok lots of suggestions thanks.

just to give a bit of context, I want to get a really good finish on this like this. its machines from mdf, due to the complex nature sanding is not welcome



so with this stuff, put it first? then spray what ever colour over the top?

The reasonably fine "engraved" features will tend to fill up with anything that might help cover rough surfaces.
The example you asked about has no fine surface detail, most likely for this reason.

You could cut the part leaving material for a fine finish path with a ball nose cutter on the detail and seal it with cyanoacrylate before the finishing cut,

the engraving was a bit of a one off, but point taken
