SEM Primer 40793 Editorial Review
Sem Products CopperweldTM Primer 40793-1 Each is designed for exterior metal surfaces, providing corrosion protection between welded substrates. The liquid form makes it easy to apply with its aerosol sprayer, although some users reported inconsistent spraying performance, which can hinder application on larger areas. While it worked effectively for some like a 74 260z floor pan restoration, others faced issues with nozzles clogging, leading to frustrating spurts while spraying. If you're tackling metal projects, this primer could be worth a try despite the mixed user experiences.
