making MDF glossy

[helotaxi 5,000+ posts]

I use Duplicolor sandable primer and Duplicolor paint and clearcoat. Works quite well. Don't use resin. It will NOT dry smooth and every little imperfection will stand out like a sore thumb once you lay down the gloss. It's also almost impossible to sand smooth. MDF is already really smooth. Just hit it with some 200 grit or so and then get out the primer.
