Alright, so for this custom, I repainted the Classics Optimus Prime figure (american release). He's a REALLY nice figure, but the paint desperately needed some touch up. I decided to make him more G1 accurate, so he'd better match his appearance in the original Transformers TV show.
First off, here's a reference photo of the original 1984 G1 Optimus Prime. This is the version I tried to mimic as much as possible.
Right side view.
Left Side view.
They painted the back of his legs blue, which is completely wrong for a G1 Optimus. This has been redone.
And here, he's been completely repainted. I covered the blue on his shoulders, the yellow on his arms, and the edges of the truck arm panels with red. Painted ALL grey areas with silver. Added silver to the pistons on the sides of his forearms, his knees, his forehead crest, and dry-brushed it over the grating on his shins. I also painted his hands blue.
Right side view. I've added a few silver details to the sides of his lower legs as well as dark brown mud detailing to his feet.
Back view. Here, you can see I've fixed the blue that was previously on the back of his upper legs, changing it to silver. This is also a good pic to see the brown wash that I added to the entire figure to help bring out all the outlining details, like the grating on his back.

Just the seats (attached to the head).
The underside of the upper body. The steering wheel is on the left side near the top.
The finished paint. I painted the steering wheel and seats in flat black and the backing behind the seats a dark metallic (black and silver mix). The front console was painted in silver. I then went over it with a light brown wash.
Just the seats.
The painted underside (steering wheel on the top left).
And here's a close up of the chest after painting was finished. I also added the yellow/gold rings on either side of his face and the Autobot symbol on his shoulder is a decal from reprolabels.
Now, one thing I thought this figure was missing was tail lights. So I went and made my own from scratch. What I did was cut a small square of styrene and then, using a hole-puncher I pushed a circle shape into the center.
Add a bit of paint and it works perfectly! In order to get that translucent look on the lights, I painted them in silver and then covered that with Tamiya "translucent red".
And vehicle mode. Front view unpainted.
Right side view. One thing I really disliked about this figure's original paint sceme is the silver striping on the roof and siding. I completely removed the silver from the roof and repainted the entire side to better match the TV show.

Underside view. I'm guessing that this is the reason for painting the backs of his legs blue, since it matches the rest of the blue on the bottom.
And the painted version. Front view. You can see here that I've added white striping between the headlights. I also gave the grating and bumper some much needed mud splatter with a wash of dark brown.
Right side view. Here, I've replaced the horrid silver striping with a simple white stripe. It fit perfectly into a sculpted indent on the truck's side. Why Hasbro didn't do that in the first place is beyond me. I also added the Autobot symbol decal to the rear side panel. It's another decal from reprolabels. Oh yes, and I painted the entire roof a solid red with a wash of dark brown.
Left side view. Another thing I added was the dried dirt effect behind the front wheels.
