I bought a slightly damaged arcade cabinet from someone that had a whole corner missing as well as some other pits and holes in the particle board. In the end, this works wonders...but it does take patience. You can't just glop a giant glob and let it dry because it will sag. So, the tactic is (and the instuctions on the can say this) to apply it in small amounts, let it dry, then apply more. For larger jobs like rebuilding an entire corner, it will take hours...but once it's dried, sanded, and painted, you couldn't tell it from wood. It bonds really well.On a side note; don't watse your time with the 4oz can...it's simply not enough for even a small job, and consideing the price difference is only like $1-$2, go with the 16oz can and be sure you have enough.
