To Robert White or RogerWhere did you buy RS 512 Medallion for $18.00 a can, it cost me about $23.00 for one can plus $12.00 for shipping? I only bought one can because I had never used it before and wanted to try it first. I really like it and want to order more and would like to find a better price. Price and shipping were the same for more then one can...Thanks for the testing Roger, Enjoy your videos!!!

If you would have put weld thru on the back side of the strips you plug welded on, then you could have cleaned up and painted that and put it outside for a test. Then in a year or so you could have cut it apart and see if the welds had rusted. That would have been a test I would be interested in. looks like both those primers weld great.

Put a teaspoon of salt in a quart of water then pour it over the piece. Store in a plastic bag for about a week to keep it damp. That will simulate about a year of outdoor exposure. Then cut it up like Shut Yer said.

Good test and good to know these are both good to weld thru ...... Unfortunetly for me I cant seem to find either brand up here in Canada......Thanks for doing these tests on weld thru primers cause at least now I know not to waste my money on the 3M brand which is crazy expensive here Cheers MrFireman ..... always good videos , learn lots from watching thanks
@Velvethamma7 жыл бұрын
I like the test. But I also agree that as the test panel became more heat soaked, the welds got flatter and penetrated nice. The 3m weld thru definitely sucks and spatters too much and I always find the can plugs up before it's empty. Even though I always purge the can when done

yes! 3m has been expensive for me in just the waste

UPOL has some good products yet some who use their fillers have said they are different as they use a lot. I am just curious like many on how both perform between the welds. I have why less spot welding to do than most. A new GM Auth tailgate seems to be thicker than the truck was build. So now I have to move the tail light pocket out to meet it. Oh well! Found rocker panel did not provide for fender relief and needs fixed. So more unplanned work to do. I just want to see the level weld protection it provided. Good job again in this test!

Hi, That was a good review, thank you for sharing it with us. I would be interested in how the panel looked after you detached the two pieces and how it looked if left out in the elements too. I am researching WTP's and the Medallion looks real good especially when compared to the upol and the price too. Kind regards Paul (from "48-SPOKES") UK

Weld thru primer is a better than nothing product, that’s why after weld I inject epoxy into the seams then seam seal the seams.

The SEM copper weld thru primer really sucked like you said you had to scrape the top off and it would splatter and if you didn't take the the top where you were going to weld the weld would come out like crap. All so for $25 a can you might get one use as the can would plug up even after you would purge the can, summit sent me a new can and it wouldn't even spray out. Looks like that stuff works!

I have issues using the copper stuff. Every time I don’t clean it off it wants to blow up and get all nasty splatters etc. when I clean it off it does better until maybe when I hit a spot I missed. If I don’t use it at all things go all around better. I did side by side test same metal same settings and it was night and day. I also noticed if I test with say a plug weld let it cool and when using the copper I sometimes here a ring sound and sure e would it let go. Don’t use it no issues. Is it just me ha being these issues with this stuff? It’s not cold because I can see burn through coming through the back. So I’m not sure if maybe it’s not mixed well,just bad or what the issue is.

Do you feel like one of these (Upol copper vs Medallion 512) is better than the other? I would think the etch weld would be better. Ive just tried the 3M Weld-Thru II but noticed that it scratches off the sheet metal very very easily. I'm currently re-banding my windshield due to rust and have new 1" wide 18 gauge strips that mate against the original base layer so I need something like this in-between the two layers where they will face each other. Each strip has maybe 10 plug weld holes to attach it to the base panel. Since I drilled them out I got a pair of spot weld vice grips off Amazon that has a thick copper backing plate so you can clamp it down and weld the hole, un-clamp, move to the next hole, etc.

Jeff Chartier honestly I like both however the medallion does have the etching factor and is somewhat cheaper , that upol Is really high but is good

The best way to do this I have found is copper weld Thru , then seam seal the seams to make it water proof also I use a syringe with reduced epoxy after it’s welded together before seam seal and inject it along the top seam and let it run down but that’s probably overkill

@@MrFireman164 I'm not sure what you are referring to when you say EPOXY. I have a two part epoxy I use on surf boards. I have two part epoxy glue and or course I have epoxy primer. I find people in different circles use the term assuming guys know what they mean. My project is complete but I struggled with this seem/weld thru primer/ burning away paint/primer issue before I had the benefit of these videos. I pretty much assume I have nothing around the welds between my lap welds. I wound up using Bondo Glass or a fiber rich roofing cement to seal them. However, my project was a work truck not a classic car.
