One of the things your fighting right now is the summer weather conditions. Any oil based finish takes longer to cure out in hot humid conditions.
Look up Timberlux's web site and watch some of the videos Brian has posted, in at least one of them he mentions the drying time issues in the summer.
Then look up Timberlux MSDS for the ingredients. It is a vastly over-priced teeny little bottle of 25% sunflower oil, 25% linseed oil, and 48% naptha, with a little dryer added. There are much better stock finishes available that do not cost over $1900.00 per gallon.
