I am currently building a new enclosure for my veiled chameleon because his current one is kind of small so I was wondering what paint should I use to paint it it is 35 inches tall 21 inches width 3 feet length
Not sure the poly acrylic will hold up. Spar urethane will work, several coats. Completely cured for several days to off gas the solvents. You could add a stain under urethane if you wish. Make sure the stain is completely dry. Remember water based won't typically stick to oil based products so don't mix them up.
