I am working on a TV stand to match my last project (coffee table.) The top is stained and the rest is painted white. I used a paintbrush first, then changed to a small foam roller for the paint. I was hoping to avoid excessive sanding for lines. Here's my problem, I applied the poly and when it dried, it looks yellow. I am assuming that some of the stain from the top transferred into the poly can. Now I have a piece that looks horrible. I have started to sand it down to the paint, but it's taking forever - my sander isn't holding onto the discs, they just fly off.. not sure what's going on there.
So, here's where I need help...
1 - Is there a better finish than poly for use over paint? Something easier, less messy?
2 - Is sanding it out the best way to get rid of the yellow poly? Since I used a roller, the paint has a little texture, so I have to sand it all the way out to get rid of it.... so basically have to start all over again with painting. :(
3 - What is the best way to use a sprayer with paint? I have used one with poly, but I'm very nervous to use it with paint. The paint I'm using is a semi-gloss so it's kind of thick. Would it be good to mix paint thinner with it?

I'm not sure what happened,
I'm not sure what happened, did you apply a finish over the white paint? Because you don't need to do that. Anyway, you might need to use a paint/varnish stripper to remove the discolored finish and start over again. Also, I use Deft clear wood finish and it never yellows. I hope this helps and that I understood what the problem was.

Just for follow up..
I have basically sanded down almost to the wood... to get rid of the yellowing. On advise of the guy at Lowes, I also changed the type of sanding discs I'm using. Instead of the cheaper red ones made with sand for the grit, I changed to the grey ones that are made with ceramic. WAY better sanding results. Sands much better and faster. You get what you pay for once again. Also, they are not flying off my sander. I would like to tell you how much longer they last too, but since I haven't worn any out yet, I don't really know. I can tell you for the amount of sanding I've done with them, I would have used at least two of the cheaper discs by now.
For the paint, I'm going to change things up. I bought flat white paint and a fresh bit of poly, plus a spray on poly. I'm going to use my sprayer to repaint the cabinet. I still haven't decided about distressing. I damaged the panel top moving it around to work on it, so I will have to fix that....

almost all poly will
almost all poly will eventually yellow, just its nature. Why not try a lacquer. One can of Deft or Minwax goes a long way and my experience thus far is great protection from water, wear and tear. and I have 3 kids!!
