Please tell me that you're not going to modify a respirator...... That setup is perfect

DO NOT use Vaseline to create a face to facepiece seal. It might do a minimal basic job against HUGE CS particulates but for smaller things such as Asbestos or other particulate or fibrous materials it just wont work. All you'll do is make yourself sick and vey unhealthy later on. I'm serious guys, if you need to stay healthy shave the xxxxxxxx thing. Same reason warriors who face the real possibility of nerve or blood agents shave to wear a gas mask. Just don't do it.
