Home Depot has 1. Stanley Powerlock 8m/26’. Had to have one for my daughters science project and took forever to track down.

Hope your not a phlebotomists.

Honestly with using high build filler primer it was pretty easy. Really just sanding the primer down to get it even. Did 2 initial coats, little wet sanding to see how it looked, then a 3rd coat and a bit more wet sanding.
