The one engine I have that is getting rtv silicone when the traction tire goes. I remember reading posts many years ago about how difficult these are. I have used rtv successfully with great results. Most of the time I replace with traction tires, but I keep a tube for engines like these. I know Bullfrog snot works too, but rtv is 5-6 dollars for a lifetime supply. Let us know what you decide and how it works.
