Lf a painter to spray my cabinet doors

[sphelps]

I'd roll a couple coats of primer on first, then sand it smooth (you don't want to start off spraying MDF as it'll absorb the primer/paint too quickly.) Then spray it with the color of choice. If you really want it to shine use a base & clear coat combination. A couple coats of base then wet sand with 600 followed but a few coats of clear and then buff it to perfection.

That'll be quite a bit of worth though and any paint shop will likely charge a significant figure as well so you might want to check out places like IKEA first as they sell high gloss panels and cabinet doors that might work for you.
