I buy my toner lacquer from Richelieu here in Calgary and it cost about $11.00 a can. I have not bought any for about a year as I don’t do cabinets in the winter. I suppose it is more than spray paint, but it is a specialized product.
If you want the cabinet to look like it has not been refinished, use toned lacquer and finish it with lacquer.
Here are a coupler of photos of ones that I have done.
Here are two links to you tube videos of cabinets I have done
I am not putting these on to show off but if done right the cabinets come out very good, and you will be very proud of the results.
