Hey Man, I have looked at alot of these Fire Pistons, But I sure like this one the best. The idea you store the oring in the top keeps it from wearing out from storing it compressed. Great Vid and the music was great too! Take care!
Alpha Bears I used motor oil - not the best choice but it is all I had around. The best thing to use I’ve been told is silicone grease which you can get at hardware stores
