tusker Posted July 30, 2011 Share Posted July 30, 2011 MEK is the best when you want to remove PRC..............recommended by Boeing!!!!!! Myself, i use PRC quite often and I wouldn't use it like you did............in a fuel Tank.....if the PRC do not cure correctly!!!.........you have to do it again. .....defuel....open panels, ventilate........... Good luck Quote Link to comment Share on other sites More sharing options...
