How do you paint?

I’m about to lose my mind figuring out how to paint this sign, I’ve tried using masking tape and then cutting, just pulled up the take around the edges, tried contact paper, and using a razor to cut it out…

What is the best method? I AM NO ARTIST! HELP ME! ARGGG

I only see his V-carve painting tutorial, might be missing it though…

Be careful when sanding, a few times now I’ve landed up making my cuts a bit to shallow and by time all the excess paint was removed I landed up sanding some of the letters away. I think I’m going to move away from spray cans and just hand paint them to reduce the amount of sanding
