When building the Jansen Walker I coated the feet for better traction, I didn't go into much detail then but I wanted to show the whole process here.
Laser cut acrylic parts are pretty slippery, especially on hard surfaces and fabrics. For parts that need good traction, like legs and wheels, it’s nice to have a little extra something.
I used plasti-dip, it’s a rubberizing dip that’s designed for dipping tool handles and it works great with laser cut acrylic.
I used 3 coats and dried them hanging up, the tricky part is hanging them without touching any other parts.
The dip shrinks considerably after drying, it’s thicker then latex paint, but not by much. I used three coats to build up a good base. Above is the wet size, below is dried.
The final product seemed to work great, I'm sure I’ll continue to use this technique on future projects. It’s easy and cheap.
