TJ here to share a couple of basic things I have used/ noticed that have helped me save time or just plain kicked ass. Let's take a look.
So the Alpha legion symbols you have seen on my Berzerkers and Oblits are all pretty well shaded and highlighted. I didn't paint each one of those painstakingly over the course of hours. NOOOO! I painted them all at once with a regular brush and some help from plain old Blue Tac.
Another thing I did was use the blue tac ($2) and stuck it to some yard sticks that I had cut in half (less than $1 each). This let me airbrush and highlight the models super fast. I know this trick isn't new and isn't unknown, but I know I thought i was fine without the sticks and man was I wrong. I based and highlighted 115 models with three colors of blue in an hour and five minutes. 115 models! I can't believe I knew this trick existed and never tried it. It costs three dollars to set up. DO IT!
The last little trick I have that I have been using lately is just mixing 50/50 Blood For the Blood God technical paint with Secret Weapon's Realistic Water effect medium. Take a look at it dried on that base. That's completely set. It looks wet and passed right over the skulls to pool looking pretty much like fresh blood to me. You could go heavier on the BFTBG to make it thicker too. I was just stoked by the final result and wanted to share it. BTW, I have used a bunch of different still water and I was really impressed by SW's formula. It just works better and easier and is very affordable compared to the alternatives.
Anyway, those are just some tricks I have tried and found recently. I think I might do something like this once in a while. Have you tried any of these? Let me know how it worked.
