Hey Koopa,
I was going to just PM you but I know there's probably more people here that might have chips and may want to keep this beast of a statue so I'm going to go through how to repair these tiny paint scrapes or chips.
You will need to be a bit steady but over all this should be easy. Also, if you're afraid of being messy cover any part of the statue you think you might get paint on with saran wrap and that should protect it from possible drips or mishandling of the paint.
You'll need three things:
1. A detail Paint brush, preferably a round brush.
2. Airbrush or Artist Acrylic Paint
3. A Matte top coat or finish, preferably in an aerosol can.
You can get detail brushes from just about any hobby/craft/art store. They're very tiny and are great for these small jobs or, as their name says, detail work. I prefer Aqualon Detail brushes but a set of 10 will cost you $20, and since this may or may not be the only time you use it, just find one that works for you.
You can buy airbrush acrylics, however for 2oz you're looking at $5-$6 per bottle and to be honest SoHo artist acrylic will work just fine and it's about $2.50 per small bottle.
The Matte coat, I prefer Krylon, but most will work just fine, and you won't be spraying that much.
Since your chips are on different parts of the statue you'll need to color match more than once. I recommend you get three to four colors of paint, you'll want an even green, in other words the closest thing they paint you chose to a regular green color. You'll need a dark brown and/or black, I recommend getting both. You'll also need a bright yellow.
What you should do is take a popsicle stick or tooth pick, or even a q-tip and use the black/brown to darken the green for dark areas and the yellow to lighten the green for light areas. I recommend doing this on a sheet of paper, and then holding up the color you've missed next to the statue to make sure you get the color correct. Repeat this step each time you come across a new shade of green, that way it'll blend and you won't even notice it.
Once you have your color correct you'll just take your brush dip it in, wipe the off any major excess and gentle dab at the chipped area until it blends in with the statue. Acrylic dries very quickly but after you've finished patching your chipped areas I recommend giving it an hour to set.
After your paint has dried, you'll take the matte coat and, this is important -
Shake the hell out of it - if you do not shake the matte coat, and shake it before each time you spray, it can, and will leave a white film over your statue and ruin it. Try to spray an even, light coat on each area you painted, and remember to shake each time before you spray.
This will dry and set in about 2 hours.
And that's it. Once your matte dries you should have a perfect Hulk. unwrap all the areas and display him proudly like the beast he is!
If anyone is afraid to try all I said here, you can always send it to anyone of the painters, yes this is shameless self promotion, in the customs area, but remember it can be expensive.
