Lucky 7 is the only thing you should use on (not in) our nitro engines..... cant tell you how many times I've dug silicone out of someone engine they cant get to tune....
Lucky 7 is a "wicking" sealant.... meaning run it around the seams you want to seal with the engine ASSEMBLED..... dont get it anywhere near the internals of the engine or it will "wick" its way inside and make a mess. The video is the correct way to fill your engine will sealant lol typical mag editors mis-using yet another product........That little bottle will last you several years
