Anyone else used gorilla tape for tubeless conversion

Re:

So pee'd off. My new wheels were already fitted from the factory with tubeless ready rim tape but I couldn't get them to seal around the valve as it was leaking around the locking ring nut. ( tried 4 different tubeless specific valves).

I thought I'd start from scratch and set it up with gorilla rim tape. But im still getting the leak on the valve.

Not sure what's my next step apart from applying puncture repair adhesive around the rubber part of the valve before fitting it yo the rim.

I will be using stans solution but this won't be fitted till I can get the valve sorted.

I've done a fair few tubeless installations, you can usually sort out minor valve leakage with the sealant, just put the sealant in, pump the tyre up and holding the wheel vertically with the valve at the bottom shake it up and down so the sealant hits the base of the valve stem. This usually stops the leak as the sealant plugs the gap.

Re:

As above^. I've used Gorilla tape and been happy, easier to apply than stans tape too. Just for info, I thought I had a valve leak, changed the valve tried all manner of ways to seal it. Turns out the rim tape had been punctured( really long nail) and the air was escaping from the valve hole, i.e round the inside of the rim and out the hole! Took a few days of head scratching!

Re:

When I applied the gorilla tape I only cut it wide enough to go close to each side wall of the rim. Should I have made it so it went slightly up the wall of the rim. I just presumed that covering the spoke holes was enough. Would this error have let air to escape under the tape and through the spoke access holes then fill the cavity up

Re:

Spoke holes is enough but no problems going right up to the edge, it can actually help seat tricky tyres by lifting them into the bead slightly.

Re:

The tyre bead has sealed all the way around. I just need to sort this air leak from the valve stem area then I can move on.

I've got to reapply the gorilla tape so ill cut it a little wider this next time

Re:

Re-applied everything but I added the stans solution straightaway.

I thought I'd cracked it but after 24 hours both tyres were semi flat. But all is not lost, I'd noticed lots of pin hole spots of sealant coming through the side walls. As this is my 1st time in going tubeless and using the solution I Googled my tyres and it turns out alot of other people have the same problem.

So it looks as I'd I just need to ride them and add more solution and they will soon hold air.

certainly some tyres, eg slightly older continental, have very porous sidewalls & can require sigificantly more sealant. with sealant inside, lay the wheel on its side & leave it for an hour. concentrating the sealant over certain areas helps it seal faster. then flip the tyre over to do the other side.

out of the tyres I've tried tubeless, modern mavic, bontrager & maxxis (even the older non tubeless!) require the least amount of sealant. where-as the lightweight schwalbes, rocket rons etc, require the most

Re:

I've had them laying on each side for a good while now, i've even given them a gentle swish around while on their sides.

All's looking good at the moment although there are a few small wet patches on the side walls still.

FWIW you can get the Stan's tape in massive rolls under the original catalogue number, rather than in a Stan's bag. Saves about 80% on the list price.
