Great question! As it is not a requirement to sand between coats when painting, to ensure the best possible finish and leave your customer happy, I would most definitely recommend it. A light sand using 220 sand paper will give you good adhesion on your top coat of gloss as well as knock down any dust or debris that has made its way into your finish. Remember only a light sanding is needed, so don't go making a mess, and always make sure you use a damp cloth to wipe up all of the sanding dust. Good luck, and Happy Painting.
Solvent based.
You can purchase a semi-gloss enamel in both water and oil-based varieties.
If using oil-based paints then most definitely.I would use minimum 240 grit in between coats and fully wipe down.If using water -based paints I would also,though paint manufacturers don't press this point.
Yes. We use oil primer on all our out door projects. Not sure why you would want to though. If I was going to put another coat on, why would it be clear? You should just put another coat of whatever color is up there now.
Because it does not mix well.
Gloss paints are available in all types of bases. The most common gloss paints used in homes are either oil based or water based alkyds or water based acrylic or vinyls latexes.
Solvent based.
No, gloss paints are typically oil-based. They contain resins and oils that provide a highly shiny finish. Water-based gloss paints also exist, but they are less common and may not provide the same level of sheen as their oil-based counterparts.
Latex and acrylic (both water-based paints) do come in a semi-gloss finish.

They include flat (matte), satin, semi- and hi gloss. It depends on if it is oil or water based. Varnish & stains offer different sheen options, also.
depending on the surface finish of the primer. Noirmally its matt in its appearance and will take a water based gloss. However, a primer should have an undercoat applied first unless its a primer/undercoat.
you can mix paint of different sheen levels provided they are of the same vehicle or base (i.e.. water based, oil based. Mixing a satin with a semi-gloss will still be reasonably close to an "eggshell" finish. The best way to know is to use the chart below and add the 2 sheen level percentages together and divide by 2.For example a low sheen (satin) is 20% sheen + Semi-Gloss which is lets say 50%20+50=70 divided by 2 = average sheen of 35% giving you an eggshell finish.Flat (1-9% gloss)Low Sheen (10-25% gloss)Eggshell (26-40% gloss)Semi Gloss (41-69% gloss)Gloss (70-89% gloss)
Yes in some cases. In my fine wood finishes, I routinely use water soluble dyes under solvent finishes. For home interior trim woodwork I often apply either water based or oil based primer under oil paint top coat with equal results. In either case, the water based product must be extremely dry before they are covered with solvent top coats.
