tattoos will be fine, do the work to keep em clean dif artists have dif advice, common is 2-3days of tattoo goo, h20cean, a&d ointment, whatever your artist recommends, then just keep it clean. sweating while boarding during the day wont ruin it. just make sure you clean it at night, they're a lot tougher than people think. one tip i picked up is use a hot compress the first couple times you wash it, like the first 2 days. meaning take a papertowel run it under hot water, as hot as you can stand, and place the towel on the tat and hold it firmly till it cools on your skin. this helps keep the scabs to a minimum. less big scabs means less chance to rip them off and potentially lose color in that spot.
