Just thought i would introduce myself and ask a question. I'm a 38 year old big kid and i am married with one 5 year old girl. I race rc cars, ride mountain bikes and NOW i am hooked on these nerf guns. I currently have 2 mavericks, 2 longshots and a recon. I have done the basic AR mods etc on these guns, no springs yet though. I'm having a ball with my family and mates blatting each other with these. I can see why these are so addictive. My question is about silicone grease, what is a good safe brand to buy? I know opinions will vary, but i'm looking for responses from guy's who have used X brand for a long time with no issues.
