Adding tubeless sealant is messy. Tim Straz thinks he has the solution.

I just break the bead, pour it in, and reseat/reinflate. Not prehistoric, no big deal really.
- Reseating has always been the issue for me. I can never get the full bead seated without an air compressor, and even then it can be hard to get that final pop
  
  Yup, it depends extremely on the tire/rim combination. Some are extremely easy, some are almost impossible to get seated.
  
  I have a compressor bottle. You pump it up with your foot pump to about 10 bar and then use that to fill the tire. Works pretty much every time.
  Here's the one I have.
I just unsrew the inner part of the valve (Schrader), use a bottle with a thin tip I've prefilled and squirt the goop it in via the valve stem, rotaring occasionally. Screw the stem insert back in, tighten and reinflate the tyre, I thought i was easy. How is it complicated?.
Don't they just have syringes you can use instead? That seems easier-er...
- They claim in the article that syringe tubes get clogged. I have no experience with this.
- If the syringe tube is wider than the valve stem inner diameter, you can't insert the tube all the way thru the stem and it's a pain in the ass to slowly fill without spilling
- Or something like a grease gun that screws or clamps onto the valve and then forces the goop in.
Just buy a stans no tubes refill bottle. 2 oz. Then keep refilling the sucker. Remove the valve core. If you're doing it the old school way it's way messier. The stans no tubes syringe was even messier.
I always seat tires before putting sealant in and this almost guarantees no splash back. https://sprocketkings.com/products/stans-no-tubes-regular-tire-sealant-2oz-bottles
- What made the syringe messier?
  
  Just like the device in the article it's fitted around the valve and the sealant goes everywhere. At least the stans syringe was over valve.
