The paint finish doesn't significantly change the surface preparation necessary. If the paint is the same type (water based going over waterbased or enamel over enamel) then the preparation is simply: * cleaning, * remove loose material, * fill any holes or hollows, * sanding and * wiping, If you are changing the type of paint (eg: painting waterbased over enamel) you may need to use an etch primer to "key" the surface and give the new paint a texture to grip onto after sanding, and otherwise prepare as above.
Enamel is a word used to describe a finish, not the formulation of a paint. It simply means a hard reflective surface. Many people mistakenly use the word enamel when referring to oil based paints. So. if you are asking if you can paint latex or acrylic paint over a latex or acrylic enamel the answer is yes, however, I strongly recommend you sand the old paint first to give the top coat "tooth". If you are asking about painting latex or acrylic over an oil based paint the answer is still yes, however you must first sand the old paint and apply a good quality primer to it. Check with a reputable paint retailer for the best brand in your area.
You can use any kind of enamel paint, but I would recommend an oil based paint, remove all oil, dirt, grease, dust and simply paint. (spray painting will give you a better finish)
High gloss Exterior Oil-Based Gloss Enamel over Quality Primer will give the best results on a cornice.
Once you have sanded and wiped down your wooden porch, use a top quality oil based primer. When that has dried apply a finish coat of latex "Porch & Floor" enamel . This will give you a durable finish that should last approximately five years.

This paint job just needs about eight more layers of enamel to give it some depth.The enamel coating is only chipped in a few places.

A primers is basically used to seal a surface and give the top coat "tooth". A primer should be chosen for the surface it is going on, oil based primers adhere better to surfaces like bare wood, slick finishes, and old oil based paint. Once the primer has dried any kind or paint may be applied as a top coat.
Enamel paint dries well on plastic. If you only need a small amount, model paints as sold in hobby stores give a great selection of colours.

I don't believe there is 'water based enamel' -that's a contradiction. Answer If your previous paint is glossy, trying washing it with TSP (or substitute) and lightly sanding it. Try the latex to see if it will adhere without bubbles. Give it plenty of drying time.
It probably isn't a good idea. The factory puts a coating (and it may be paint) on the heater when it is manufactured, and that should be it. Painting the heater will cause it to give off some "fumes" from the paint the next time it is used, and for a number of times after that until the paint fully cures. And it's not a good idea to be breathing that stuff. As bad as a finish on a heater might be, clean it and call it good. Painting could expose you to some bad news.
There are concrete paints available. A three step epoxy paint give a very attractive finish. Both products are available at Lowe's or Home Depot
