I painted for 6 years, thru college. We always used an oil based high-gloss finish on trim, doors, etc... While it definitely produced a really nice finishd product, there were downfalls. The big one is, the white oil based paint 'yellows', in other words, the color fades, if it doesn't get exposed to natural light on a regular basis. The other downfall is the clean-up. Working with oil based paints is a pain, the thinner is expensive, if you get oil-based paints on your skin you have to use thinner to get it off, which can be painful and cause mild health problems over a prolonged period. I recently painted a house with latex based high gloss finish on the trim. While the finish was good, it wasn't quite as good, but only the painter noticed, honestly. The home owner was very pleased. The latex of course is so much easier to work with and the color doesn't fade or yellow. My recommendation, work with latex whenever possible.
For the best possible shine, use a high-quality primer, like KILZ, latex or oil, but if it's a wood that the grain might raise, use the oil-based primer. Use two coats of primer. We usually spray everything to apply the paint, but when applying the latex based primer to the walls and trim, we brush the trim to smooth it (and remove any debris that ended up in the trim) and we also roll the walls. Even though we brushed the primer to smooth it, we still usually sanded (by feel) before spraying the finish on the trim. Make sure the trim is dust free, no oil or grease on the trim, and paint away!! If spraying, use a fine tip and double coat. |

If this is a polyurethane coating, then you can wet sand it and polish/buff to get a high-gloss shine.
- Make sure the finish is allowed to fully cure per the manufacturers directions.
- Wet sand with with progressively higher grit (smoother) emory paper. Don't use regular sandpaper, it's not designed to hold up in water.
- Buff and polish with and rubbing or polishing compound. I would recommend using a power buffer...but be carefull, you can reck your finish if your not!
