Just ordered a Vortec Tune Kit so needless to say it's all apart on my bench cause of a busted spring.(Bummer)I picked a tube of Green Grease, synthetic polymer Anyone out there ever try this on there gun?In the looking I've been doing there is Black Tar for the spring and other grease and oil for different parts.Is the grease and oil used for one part or the other part really that important or can one be used for all the parts?
