I had a client of mine in newport beach (cab driver) get tattooed on his left arm it was summer time and he wasnt the brightest color in the crayon box but a great guy, anyways i did a Shawn Warcot frankenstien flash piece on his left forearm he drove around all day with plastic wrap on his fresh tattoo all day in 100 degree he came in the next day with his tattoo about 2 inches raised off his arm and green puss spewing out of all of Frankenstein s features. i washed it and wiped off the Quarter inch thick layer of slimy foul sun backed skin and told him to come in every other day so i could see how it was healing up. it took 3 weeks and one touch up to be good but lesson learned i never let a client leave without specific instructions on no sun exposure!!!!
BTW: that was in my second year as an tattoo artist
