Professional vs rattlecan
I also bought Ron skids in raw form and if you have painted cars before you can get a similiar quality from using auto paint in spray cans.
It takes more elbow grease-I prepped and sanded between coats and laid paint in several layers and thickly which is much easier using a gun/compressor. You'll need to find a dust free area too, such as a garage versus someplace dust motes and that one large bug attracted to the paint.
The key here is patience and elbow grease and lots of sanding.
Anyway, if you have more time than money it can be done and still look professional.
