I'm going tube less I have Shimano UST rims and Michlen tires. Can I add sealant, and inflate them with a CO2 inflater? I can use a neighbors compressor this afternoon for the initial setup, but if I'm going to need one every time I inflate a tire I might as well buy a small compressor right?

compressor will be cheaper in the long run than all the CO2 cartridges you'll waste

You might get lucky and be able to seat them with a floor pump. But if not, and you buy a small compressor, it should have a tank on it for decent volume.

If the tires are tubeless, use some soapy water and you should be good with a floor pump. As long as the tires are new should be a piece of cake. The hard part is when the tire is not new....

Whatever method you use, remove the valve core first to get it to seat. It seems to let more air in quicker which has helped me before.

be prepared to pump like a mad man if need be.

I have succeeded with a couple of mounts using a tiny pankake compressor with a 2 gallon tank since the failures I documented here:

I would not have wanted to try that with either C02 or with a hand pump. It just would not have happened.

Sometimes a tire/rim combo takes a couple of tries even with the small compressor. Just not enough volume to keep the air going more than 15 seconds or so before the pressure is too low to help pop the bead.

I mounted a cheap Maxis Ardent yesterday and I needed a compressor. I had to put a tube in it first to get one side to seal, not too hard after that. Stan's sealed the tire within one minute . CO2 will leak through the tire walls and through the valve stem because the molecules are much smaller than regular air.

I've had success with a pancake compressor on non-tubeless tires mounted to non-tubeless rims. The big volume Ardent 2.4 on the front takes an awful lot of air flow while simultaneously fussing with the tire to get the beads to pop in.

If the tires are new, you might want to install them with tubes first and leave them in the sun to soften them up a little and get the creases out, if any.

Also, instead of the "Stans shake" after the tire is first mounted tubeless, I grab the tire at the 4 and 8 o'clock positions, lean over and bang the far side of the tire against the ground, rotate a couple hand widths and repeat until you've rotated 720 degrees or so. Flip over and repeat some more.

The tire I installed this way on Sunday has been sitting at 40 psi since then, and I never bothered to look for leaks with the soapy water.

this ^^^^^^^

Harbor Freight has a 1/3 Horsepower, 3 Gal., 100 PSI Oilless Pancake Air Compressor for cheap.
I paid around $40 for mine.

Did the inflate today with my new compressor, it worked great. I don't think it would have gone so smoothly without one. My take after doing it this morning is, if you want to go tubeless but are worried it will be a messy pain in the butt. Don't be, buy the Stan's injector and squirt the sealant in after the tire is mounted on the rim. Then hit it with the air, and viola no leaks and tubes!

You don't even need the Stans injector. The Stans bottle I have had a cone shaped funnel cap option. If you remove the valve stem and are careful, you can fill the presta tube straight from the bottle. Just squeeze the tire slightly to reduce the air volume with the presta valve in the up position, put the bottle into the presta tube, rotate the tire on the bike so that the valve is in the down position and squeeze in a liberal amount of stans. This is how I recharge my tires without breaking the bead.

The nozzle on this little filler cap used to clog, so I reamed it out a little with a drill bit. Now the stans flows into the tire fine without plugging the dispenser.
