Attend Republican meetings and dress like you are going to Court. Shave and long sleeves can cover tats. The idea is not hide who you are, but rather make a good first impression. You want to make friends and not be prejudged. Many of these folks have put years into the GOP and want you to earn your stripes. Working as Election workers can be a big plus.
Republican Aux groups are ripe to be taken over. We need WOMEN in the Women's Groups!
