I've been wanting an MCU Dr. Hank Pym for a good three years now, Imagine my surprise when I found this kit on eBay!
The seller still has some for sale; his name is whitestoysds.

I immediately grabbed one (grab yours today!) and set to work.

I painted the hair a medium grey and then dry brushed some white onto it; same for the facial hair and eyebrows. I mixed a lighter skin tone up for him before going over his wrinkles and lips in a darker skin tone to really show his age a bit. I removed all of the lettering and symbols from his Loki jacket with some paint brush restorer. I couldn't get the TVA symbol off of his belt so I had to paint some brown over that.

For the Hot Wheels Rally Case, I cut out the decals, brushed some Krazy Glue on the case, and placed the decals on. Easy peasy. Then I popped the glasses on, and voila! Now I own one of my biggest MCU figure wants, and I'm thrilled to add him to the shelf.
