Hi all More advice needed please. This time round I'm working on the bonnet. I have used a da and took it back to original primer and in some areas gone through to the metal where stone chips has rusted through. So my question is shall I epoxy the bare metal area then use a barrier coat over the hole panel ? Then base and lacquer ? On the wings I done earlier I took it back to bare metal so I epoxy the hole wing so was straight forward in prep etc. Also I used epoxy 421from rustbusters but have now ran out . So advice on an alternative epoxy primer please . Learning as I go so be kind. Best regards.
