Is that a galvanized metal Rob? It's interesting that the white on the bottom doesn't seem to be failing, at least in the pics.

I think the deep base just couldn't handle the heat, white is intact. It is only the front side (gets the sun worst) they want done. It is galvanized, have not bid it yet, still debating.

They likely didn’t etch the galvanized metal first, so whatever that first layer is - it’s failed. If you don’t strip it all now, whatever is left on will come off later.

Gabe - Wouldnt he need to use a Wash Primer for the galvy? Probably why the previous job is coming off in sheets to the metal.

I'd pressure wash [with chemicals}...let dry and apply a galvanized primer.{if needed}

Then top coat with a Devoe DTM product: Devflex HP

It says you don't need a primer if prepped properly..I'd look into that...
