FIXED IT!! Ended up grabbing a can of refrigerant w/ the dye and some sealant in it (Arctic Freeze @ Advance). Cost $30 cause I got the cool trigger gauge and black light pen w/ it. Took it home, ran it through...sure enough little leak right at the a/c compressor. Did that Fri nite and haven't seen a decrease in pressure yet, so looks like the stuff sealed off whatever little leak there was.
