I have tried Stan's which works really well but has caused some corrosion on my Dura Ace wheels. Probably because the DA rims are not anodized. Tried Slime as a substitute but that does not seem to work very well at all. Flat this AM. Road tubeless. Maybe you need to fill the tire completely with slime? I had lots in there but..

Is that Orange stuff any good? Any real experience? I have read less that stellar results about Caffe Latex.

There is a lot of construction on my rout in these days and I may have to resort to the mountain bike to commute.

i've used stans pretty much exclusively but my rims have always been anodized. slime by itself doesn't work very well. i had a tire blow off the rim once with slime. i think the ammonia in the stans is what causes corrosion. there are some home made recipes for sealant that you can probably rework to get rid of the ammonia. it's mostly liquid latex and glitter.
How we spend our days is, of course, how we spend our lives.

The Continental stuff is ammonia free. I think it's called Revo or something like that. It's all I've ever used, and when I replaced the rear tire I noticed lots and lots of little rubber balls that formed due to sealing small punctures. So far so good.

I'll see what I can find at the local shops. Maybe conti or Caffeleatex as Zinn says he's had good results with that.

I usually use stans for the MTB. I have used Bontager in the past because the shop was out of stans and it did fine, not a fan of the orange seal stuff - it was crap. Supposedly the glitter in the Bontrager helps the sealant fill a bigger hole

Man, we could have a whole thread on tubeless tricks and work arounds for road and mountain

No guff eh! I used Bontrager twice off road. The first stuff was thickish green stuff and it worked fine but disappeared after a few months. Tire was loosing pressure so I opened things up to top off and there wasn't even a residue left. The Bontrager I used this summer was more like Stan's but a bit thinner and white too. Worked very well and lasted a long time. I may try and find some of that because it might be glycol based as opposed to latex. Although maybe the fist gen was glycol and the latest is latex.

Vittoria liquid sealant is good stuff and claims to not be corrosive

When I was racing cyclo-cross I had Tufo tires and Tufo had some pretty good latex sealant. It worked against all those goatheads we have sprouting up in September-October in Colorado. I don't know if they still make it and/or still sell this stuff in the US or North America.
For my MTB I use Stan's too on Mavic CrossMax wheels, I haven't noticed any corrosion but then again my wheels are really beat up anyway.

Another thought I had was to clean up the rim bed really well to take off any sealant residue and take out the corroded bits to bare metal and paint it. I have a number of paint pens which i think is model airplane enamel that I have used as touch up paint. I could easily paint the entire rim bed with that. Then perhaps I could use the Stan's?

The shop is going to ask the Shimano rep about sealant's that are acceptable first though.

There are lots and lots of reports of Shimano wheels being adversely affected by Stan's, just like yours. I've only got one data point on road tubeless and that is with Hutchinson Fusion 3s, Stan's goop, and Stan's tape on carbon wheels (Rails). Knock wood, no flats in a lot of miles and I like the ride a lot. Trying out a set of Galactik (?) next.

The Orange Seal works very well, I have had a couple of sample bottles, the stuff works great tubeless, and in tubes. The only drawback is that I hear it's about twice the cost of Stan's

I ended up with some Bontrager stuff that has no ammonia. I buffed the rim clean with acetone and scotch brite remounted the tire and discovered at least two punctures. That green thick slime was useless at sealing. Decided to use a spare fusion and the bounty sealant. All good now.
