Using Japan drier to reduce tack time

Has anybody tried using the Rustoleum with some Japan Drier added to the mix?
Japan Drier is a hardener for oil based paints such as Rustoleum. I think this may cut the drying time considerably.

I saw this at True Value the other day. Wondered the same myself.

I did some research on this. The japan drier works ok. I cuts the drying time quite a bit. An enamel hardener works much better.

I found a hardener at O'Reilley auto parts that is designed for alkyd enamel. This stuff works great with rustoleum and penetrol. I brushed my door jambs with this mix and they came out like they were sprayed.

If O'Reilleys doesn't have it on the shelf. they can order it.
