I'm going to give it a try rather then buying a new door.
I have a wooden door (veneer on both sides) with some decorative mouldings. My plan is to use a heat gun to get as much paint off as possible and then go around with an orbital sander using 80, 120 and 220 grit sandpaper.
On the bottom, the door is weathered and some of the wood is chipped or has started to flake under the paint. I think I need to use some kind of filler but I would like to know what kind because I want it to hold.
Also, one of the biggest issues with restoring it myself is that I don't like seeing brush marks in the paint. So, I plan to paint the door using a sprayer. I do have the equipment for painting cars. Can I spray the door with the same spray gun? What kind of primer and paint do I need to use on the wood to make sure it holds well and lasts for a long time?
Any other advice on stripping, sanding and filling the paint will be appreciated.
Note: If it makes a difference, I'm also going to get all new hardware.

We just use good ol' bondo to fill missing pieces in wood. In the cabinets I did last weekend, several of the doors had an inch worth of corner rebuilt from bondo.
The other tool that helped us that weekend was a profile detail sander; specifically the octosander by Skil.
You can use the same spray gun you would use for cars, but you might need a larger diameter tip/needle combo. With my gun, I need a 1.7mm tip for oil based enamel and a 2.5 for water based.
Edit to add our process:
Dad has always used exterior-grade Alkyd (Oil) based finishes on wood doors. Due to VOC restrictions, many of the finishes he used are no longer available, and the newer low-VOC formulations are prone to chalking. Our paint store, who I trust implicitly, now recommends that we use an alkyd primer and then coat with an exterior acrylic.
