Looking for a suitable primer for use on a machine accessory that I'm
building at the moment.
I want a good foundation so that a top coat is likely to stay on and not
blister off or chip too easily in normal use and handling.
Aerosol or brush application and readily available if at all possible
Materials involved on this project are a mix of black and bright mild
steel and MIG filler wire.
This item is 2m long so no opportunity to use "her" oven of any heat
treatment even when " she" is not looking!
Something that could also be effective on aluminium alloy for future
widgets would make the primer even more attractive but not essential.
Any suggestions please?
