Review and Using Weld Through Primer
Craig HopkinsDescription
Craig Hopkins gives a review of his preferred weld through primer – Medallions rubberseal RS512. He claims this is the best weld through primer he has ever used despite what others say. See how to apply a thin coat to the bottom of the panel.
At the AMD Installation Center, we always strive for a quality build, and you should too. Medallion's Rubber Seal RS-512 weld-through primer is the best primer we've ever used. I talk to a lot of guys, they say, "Hey, we've used weld-through primer, it's problematic. But just a thin coat of this, I've never had a problem." It doesn't take a lot of weld-through primer, but it does help. Now, give the bottom of the panel light coat also. And then, just where it's bare, won't take much. You know, whenever the camera guy asks me a question, I think I wonder who else has the same question? And the question was, "Are we gonna spray the other side?" And, no, we're not. The weld-through primer just goes between the panels. Now, the camera guy, Mr. Bill, as we call him, is getting educated, and before long, he's gonna be building cars also. Just between the panels, not on the top side.
I have tried Eastwood and SEM weld thru primers. All instructions say to apply primer and then grind to bare metal where the welds are to be. I've tried to weld thru these weld thru primers and it doesn't work. Is Medallion that much better or is something being left out? What changes need to be made to welder settings?
I can't find the Medallion Rubber seal 512 anywhere do you know where to purchase it from

Rubber seal products have been the best products ever. I’ve been using their primer and cleats for over twenty yrs now!!
