I plan on buying the EW flat black hotrod paint kit to use on my steel 1926 coupe . The kit comes with epoxy primer and the flat paint . My question is can I use the USC high build primer first over the bare metal and the body filler skim coat , then the epoxy primer and topcoat in the kit ? I’m not very good at the body work thing and I figure it will take me a lot of work to get it to look right and don’t want to keep spraying the epoxy primer that comes with the kit and sanding it back off . What do you think ? Thanks in advance . Chuck
