I think I may need to replace the piston seal on my whisper, need some advice. I'm building my spring compressor now so I can take it out. The seal is one gene put in so I will just us my micrometer to get the proper size for it. My question is do I clean all the old tar out of the chamber and what do I you use to clean it with, what lubricants will I need and how much do I put on. What do I need to know about taking the trigger assembly out.
Thanks
Jeff
