Well it's up to you bro, Depending how hot he bakes it at, i usually take em out since i have access to a press. Other people had them in with out any issues. I dont think it's going to get hot enough to melt your rubber away (thats what she said) LOL, anyway if you dont have access to a press or you dont want to go through the bullshyt hassle of takin em out, leave them suckers in there. Dont forget to post pics too.
