As a Warhammer painter and a graphic designer, there are certain tools and materials I'm always using. Here are my essentials.
My standard primer for Warhammer models. It goes on so smoothly that you'll constantly get comments asking why you didn't use any primer...
Rustoleum Flat Gray Primer
My favorite plastic cement for Warhammer models.
Tamiya Extra Thin Cement
The humble X-Acto knife. Buy many blades. Many many blades.
X-Acto #1 Knife
My favorite super glue for metal and resin models. A six-pack will last you ages.
Super Glue Gel 6 Pack
A big old bottle of Elmer's Glue. I use so much of this stuff.
Elmer's Glue - 128 oz
This stuff is truly miraculous. Print your own waterslide transfers on an inkjet printer. I use this for all my custom Warhammer transfers.
Sunnyscopa Inkjet Decal Paper
This stuff is great for sealing cardboard and paper before painting with water-based paints. It feels like plastic when it dries.
Mod Podge - Matte Finish
This stuff is absolutely amazing when it comes to making easy hills, mountains, and other terrain. So simple to use.
Sculptamold - 3 lb
I use these to spread acrylic paint on boards, to smooth down wheat-pasted paper, and about a hundred other things.
Plastic Taping Knife (3-Pack)
Essential for mounting paper, even temporarily.
Multi-Purpose Spray Adhesive
The best matte varnish I've tried so far.
AK Interactive Ultra Matt Varnish
My favorite miniature brushes. I go through them quickly, so I try to buy cheaper ones.
Nicpro Detail Paint Brushes
Perfect tape for masking areas on posters, paintings, models, etc.
0.94 in. Painter's Tape
Your basic sandpaper. I use this to add texture to posters, smooth parts of models, and so on
Fine 220-Grit Sheet Sandpaper
My kids and I love this paper set. I use it a lot as backgrounds for Warhammer model photography.
Neenah Astrobrights Paper
Some Warhammer painters love wet palettes, but I prefer a standard dry palette. The Warhammer one was discontinued, so I need to find a replacement.
Blick Studio Palette Pads
Cheaper (sort of) than Warhammer texture paint, this stuff is great for sculpting bases and adding character to terrain. You can add rocks, sand, etc while it's still dry, and then paint it later.
