good news at last. looks like a run to the auto parts store is in my near future. could you be more specific about exactly which black Permatex? the number on the tube? there are a couple I found online.
It's not actually "Permatex", sorry, my mistake. It acts just like Permatex though, that I've used before, I got confused. I bought my tube at the hardware store about 3 years ago when installing a pellet stove. I don't normally shop with Amazon but here's a link where you can read some reviews. Very sorry about the mix up  . |

The bench testing is tough on the rim seal, but you have to do it. Thanks for sharing Gale.

Hopefully it works. I have to use Sili foams on anything that runs over 40 MPH and they are fairly expensive and hard to find.

Guys, Maybe this was brought up before??? But I've used Pematex Windshield and Glass Sealer (Flowable Silicone) with good success. I hope this might help?

I got a RTV gasket silicone From JB Weld. It was black and the other was red or blue, the black was the choice. Let you know how it works after a few days. Its calling for a 24 set time.

I think its working very well. Its a very sticky consistency, the tires stayed on at 14 volt blasts of power. Did up the third set tonight and will start rolling on test passes mid week. I think this was a real good tip. Thank you Sir

Guys, Maybe this was brought up before??? But I've used Pematex Windshield and Glass Sealer (Flowable Silicone) with good success. I hope this might help? I have some of that, will try mounting some tires with it and post the results. The flowable silicone is what I have used for a long time, but I found that it won't hold on an Inline Comp or better build. That's when I switched to the IC 2000 and have had better results, but the tires will still break loose on an Inline Comp + build. 4 Gears do better mostly because I am usually stretching the tire on an oversized rim. I am experimenting with some hard compound silicone slip ons now. They are hard to work with and they lose a lot of grip over the softer compound for obvious reasons. Silli foams are the way to go but they are pricey and only a few options. I am paying close attention to the testing going on here. It would be great to be able to use slip ons without slinging them off mid race. Thanks for sharing guys! |

I would doubt any of the compounds shown here would stay on with the Unlimiteds. Those 50-60 MPH speeds seem to throw anything off. Even the Silifoams will start to peel after awhile.

I had one tire that let loose tonight. The others are staying very well under full load. This was the first axle set if that means anything and was only one tire. I will redo both tires.
Im thinking right along with Dave, faster than 25 mph your up at the limit of the bond with slipons and glue.
Next might be contact cement. Trouble is your working with at least one very smooth surface and the rim you can only scuff so much. I have taken an exacto and scratched perpendicular lines on the rim in effort to gain adhesion. Not much more than sand paper and a good cleaning on the silicone tire. I clean with Xylene as it is a reducer for silicone.

Second fail. I think back to the CA glue and hope for the best.  |

As we reach 30 MPH or so most glues fail.

I re glued the tires with rtv. One tire was holding on each axle so I decided to give another try.
