I’m currently restoring my 67 MGB GT and obviously I would like to protect the repaired metalwork as I go,(at the moment I’m working on the inner wing that will be open to the elements) my problem is the differing points of view I keep coming across as to the pros and cons of under seal,( what I would like to do is seal the panel joints with a seam sealer and then apply two or three brush coats of epoxy primer followed by a top coat, I would be very grateful for any advice, many thanks Vin
