MG MGB Technical - Priming new panels

As a first step towards the final respray I'm happy with the idea of etch priming bare metal, but what's the first step of protection for new (Heritage) panels with their black finish? Do I go straight for the filler primer after a gentle sanding?
Richard Coombs

I believe the shells are primed with an E-coat primer, jsut sand and shoot with your filler/primer

Richard:

John is correct. The Heritage panels are all E-coated, but the bonding to the metal is only as good as the cleanliness of the pressed steel. You can just scuff sand and primer since the finish on most of the outer panels I've seen is good, but for the best top coat protection the outer surface should be sanded to bare metal, then etched.

Forget the etch primers (old school) and use a good epoxy primer. On top of this you will shoot the high fill or polyester primer that you will block sand until you can't stant it anymore. Then you shoot a sealer and finally the topcoat. Simple.

You will probably pass out when you see how much the materials cost.

Thanks everyone.
Pete, well you may know that MG stands for 'Money Gobbler' so after 10 years I've already gone way past a viable bank account!

Hi Richard
I restored mine in '95 with new panels, I degreased the electro primer that the panels came with, primed them with grey primer and then glossed them [all celly] the finish is fine after 12 years use with no problems with paint adhesion.

Thanks Ron. Very encouraging. I'll go the same way I think and put most of the effort into the 'old' bodywork.
