Sploosh!
The anti tubeless crew is gonna love this one.
I took a significant drop at significant speed and upon landing tore a hole through the tread of my tire. I put 3 dyna plugs in it and it held but the rim was dented and leaked out. Trailside TPU tube and I rode another 8-9 miles back to my car.
I decided to beef up the rear. I replaced the tire from EXO to EXO+, in addition I added a Vittoria XC insert. All pretty light stuff but should offer more protection than previously without major weight penalties since I ride up hills too. Once I bent the dents out, I wasn't fully convinced that I wouldn't have a leak at the bead. The rim rolls straight and the hop is not noticeable, I'm not ready to rebuild the wheel yet. I had a Fatty Stripper in a drawer that has been waiting for the perfect situation.
I went for the much off sealant since it's way thicker than the orange stuff.
Thicker than average tire + foam insert + latex rim strip cover + thicker sealant + standard presta valve
Using a syringe on a tube the first 2 ounces went in fine (60ml syringe), the next syringe full it wouldn't push past the valve. I fiddled with it and gave it some force, and sploosh. Facefull of sealant, all over the back deck, and not in the tire. I couldn't find a way with only 2 hands to do it for a minute, took another facial trying. Finally I managed to pinch and elevate the insert and create room to get more sealant through. It took some fiddling but I finally got it in. Hopefully it leaks past the insert and becomes useful on the tire side. Those clothes are going straight into the garbage.
I've never ran into a situation where it was better to put the sealant first. This may have been it but the liner and stripper would probably have made the whole process near impossible. This is why Cush Core uses specific valves.
Good times. Hopefully it'll be the end of next fall before I have to do that again.
