I filled the grain with some Constantines red mahogany grain filler. After it dried, I lightly sanded the cabinet and sealed with Deft lacquer sanding sealer.
I managed to get a couple light coats of Mohawk cherry/red mahogany toner lacquer on the cabinet before the temperature dropped 40F Thursday night

It might be a while before I can put on some coats of clear and rub out the finish.
I'll keep plugging away at the electronics in the meantime.
