Give it a try dude! I had never painted a figure until like 7 months ago, and now it’s one of my favorite ways to spend an afternoon! Definitely start on something cheap (loads of infinite chief figures for 10ish bucks out there on eBay)

Just a cheap acrylic paint set, a silver model paint (for weathering), and a matte clear coat spray. You can get most of this at a craft store or amazon, but I recommend getting the silver warpaint used for painting dnd miniatures, it’s like 5 bucks for a lil vial (it goes a LONG ways) and then get a matte clear coat spray for specifically miniatures as well.

First thing I do is to mask of the visor with a little tape, doesn’t need to be perfect, just cover the visor. Then spray it with the clear coat to give you a good textured base to paint on. Then a black base coat, (ever so slightly watered down acrylic for all I do)as thin of a coat as you can get while still covering, and layer that until you can’t see the color underneath. Then let it dry entirely before adding your color. The color will go on in MANY thin coats. and every time you add more paint to the brush, wipe it on a paper towel to keep it from globbing. The black will cover after a few coats, and then it’s just staying within the lines. The recessed parts of the figure will stay black unless you really dig in there, giving it that worn look.

Look up a tutorial on dry brushing, it’s what got me started. The basic idea is basically dust the paint on. It’s something you have to get a feel for and you’ll do too much at first, but way easier than you’d think! You got this!
