I'm going to document the gradual progression of my husband Dean's Firewire surfboard. Not sure when I'll stop, as the more I do the more he wants. Perhaps I'll take it to the waxed area midway. Sanded board, clean hands and arms are a MUST! I'm using paint pens by Posta, mostly the extra fine point black. Have rubbing alcohol and cotton balls on hand for quick swipes if pen leaks (or if your child comes up with their fingers and leaves a smudge). The board needs to remain CLEAN.
