Iam wanted to seal this thing up before I cause some damage. I don't mind spending $60 bucks for the shield from Highlifter, but if I can put some silicone on the pull starter to seal it I might go that way. I want to know from both sides. Does the silicon start to leak after time? What silicone to use? And if that shield ever warps and needs any mant. on it either? I have read the How to Section and it looks really easy to do. I just want to know if it is better than the shield? Thanks for any help.
