It looks almost like alligator skin... or like when you have wax and you put liquid on it, all the liquid seperates like it won't stick. Thats what my polyurethane is doing right now... how do you fix it? And why is it doing that?

You might be putting it on too thick. Just a thin, even layer will do, then let it dry completely before you decide if you want a second coat.

It may well be in your brushing technique, and in the brush that you are using. First - purchase a brush intended for use with polyurethane or stain. This brush will NOT be cheap, however, for a few dollars more, you have a brush that could last you a lifetime with proper care. Second, ALWAYS maintain whats called a "wet" brush when applying the poly. Don't scrimp...brush from the "wet" poly you just applied to the unfinished area. Keep plenty of poly on the brush. Don't allow it to "drag" (if it drags, it's too dry). Honestly I'd use a high-gloss oil based polyuethane, it'll take the pounding that tables take much better than the water based products. Allow each coat to dry per the manufacturer's instructions on the poly can, lightly sand with #000 steel wool between coats - this will remove slight bumps, bubbles, etc. Face it - it's NOT going to be perfect but if you follow the above directions, it will look very good.

There is a contaminant on the surface you are applying the polyurethane to.
It may be an oil soaked into the surface of the wood.
If it has penetrated into the wood, even sanding the surface may not remove it.
Oils can penetrate deeply.
I haven't a cure to suggest but I would consult with a knowledgeable specialist . There are sealers that can be applied prior to applying the polyurethane that may help.
Go to a specialty "paint" store such as Sherwin Williams and talk to their representatives or find one on the Internet.

Wipe it down with a "deglosser" first to clean contaminants off the surface...then sand lightly with 220 sandpaper...dust and try that....deglosser..also labeled as liquid sander is available in all diy stores or walmarts...also is some nice products put out by "flood" that will work such as this link...
