So first task is to look into a wet pallet i think. Any tips would be cool
Wet pallets are extremely easy to make and help tremendously. There are a bunch of tutorials around.
What I did was head to Target and bought an airtight tupperware tray (brand Sterlite) with a lid that snaps securely closed. It's maybe 12' by 6" or so. Then I got two sponges that - side by side - filled up most of the floor. Fill the container with water maybe 1/2" or so (enough that the sponges can stay consistently wet). Then, parchment paper - just cut a piece that is the size of the surface of the sponges and lay it on top of them. It'll curl up at first - once it does, flip it over. If it curls up again, just flip it over again. The parchment paper is, of course, your new pallet surface. Soon it'll be fairly snug on the sponges. Then - paint!
When I started using it I was really surprised at how much paint I was saving as it can last for *days*. Also, if you're mixing paints, it ensures that your mix is consistently the same, as you're always using the same paint instead of remixing for different painting sessions.
