I just wrote this up for another forum and figured I'd post it here as well, someone might find it useful
I got tired of looking at the primer grey faceplate on the GH3 guitar today so I decided to paint it up and document the process. The original plan was to paint it up to match my Halo gear but I'm getting bored with weathering black items so I'm going to paint it up like the Mark I Iron Man gear I'm also doing.
Step 1 was the primer, nothing fancy, just regular old grey sandable primer
Step 2, Hammered metal paint:
once the hammered paint was dry I hit it in a few spots with a blowtorch to make it bubble more.
Step 3, the black coat:
I'm using Citadel brand paints for the coloured coats, the black is Chaos Black.
Step 4, removing the black:
Once the black was dry I took most of it off with some 600 grit wet and dry sandpaper (you could use a scouring pad or something similar, I just hand the sandpaper close by)
Depending on the piece you may need to add an additional coat of black, the guitar face doesn't look quite right to me so I'll be adding some more black as well as some browns and green.
I used both Scorched brown and Bestial brown.
and a little green thrown on:
The green is Goblin green.
Removed most of the paints last night and wound up with this:
It's a little too rusty but that's an easy fix. I managed to get some of the back done as well:
There's still a bit more work to do, mostly hand painted weathering, but it's looking pretty good and it matches the Mark I Iron Man helmet
I'll post some more photos of the rest of the guitar as I finish it.
