Carpentry and Woodworking - Wipe-on Poly vs. Paint-on Poly

I am about ready to stain and finish a straight grain fir bunk bed I've been building. I have heard about a wipe-on polyurethane finish that will help me avoid those nasty bubbles. Has anyone used it? Any drawbacks?

Also, is there a FAQ on this site about sanding and staining tips for softwood (like Fir)? I've looked and can't find it.

From what I've heard on this forum is that the wipe-on poly is just thinned out poly.

I've used both types and each one has it's particulars.

For me, the wipe on poly was so much easier to use and I didn't get any bubbles.

Bazooka227 is correct.

I make wipe-on poly all the time, 25 to 50 percent mineral spirits.
Because it is thinner, the bubbles burst before they have time to set.
Of course, because the coats are thinner, you may need to apply an extra coat or two.

Poly is not bad to put on but you must adhere to some certain facts. Never shake the can, never remove excess poly from the brush by wiping it in the lip of the can (it will add bubbles), use the correct brush. There is a tapered brush used for applications such as poly. I obtain smooth beautiful results by following this. Also make sure the surface is clean.... I mean really clean.

There are certain woods that stain will raise the grain on. A water base stain is more inclined to do this that oil based.

A company called general finishes makes a poly varnish that you wipe on using a lint free cloth. Works really well with no streaks. Apply a little thinner because it can run on you. Just make sure you get the surface wet and you will have a nice covering. Also, make sure the cloth is lint free. Old T-shirts work well. Go on the internet and do a search for General Finishes.
