Warlord Games is now doing their own part to help your caffeine-hands with waterslide decals for Bolt Action (or really anything, but they suggest you use them for Bolt Action models).
From the announcement:
You’ve asked and we’ve delivered – these high quality waterslide transfers are designed to go with our 28mm Bolt Action vehicles. The first eight sheets are available now!
These decals will finish your vehicles off perfectly and they are very easy to apply. Simply cut out the desired decal, leave it in a dish of lukewarm water for a few seconds and then slide it off the backing paper and into place. Using a clean paintbrush will help in the positioning of your decals as well as making sure they are free of trapped air bubbles.
