I just bought some from Eastwood but I can't say how good it is yet since it is still sitting on the bench

I don't think I ever used any tools or materials from Eastwood but I've always wanted to try them, not sure what I think of that company, a lot of them seem to sell the same stuff just re branded, for some reason I place them slightly above Harbor Freight in quality in my mind, correct me if I am wrong |

Re: Where you all get your weld through primer these days?
So far "knocks on wood" I have been pleased with everything I have gotten from them. I am still in a learning curve with the powdercoating gun though lol

Re: Where you all get your weld through primer these days?
I will say I have used a lot of weld through primers at work over the years ,the company I work for has about 10 to 12 crews out in the field, and we all at some point recommended to our shop buyer that U-pol was the best weld through primer, I do not remember what type it was because there are a few , but the can was green and as for price I have no idea , but I remember the 3m stuff was terrible after a couple uses the can would stop spraying and that was every can ,so it was not just getting a bad spay can, because every crew complained about it.and most if not all of the other stuff we used had terrible adhesive qualities, it would scrap off easily .

not weld through primer, but here is a link to an excellent spray paint primer with a great nozzle and good coverage Rust-Oleum 249330 Automotive Rusty Metal Primer Spray Paint for $9 bucks so about twice the cost of others but worth it, comes in light gray too |

Re: Where you all get your weld through primer these days?

Copied from the H.A.M.B. Weld thru primer is used in modern collision repair to replace the zinc coating imbedded in modern sheet metal, only when it is ground off during the repair. It was designed to be used ONLY on bare metal mating flanges. And YES you weld right through it. Absolutely NOT for use on the inside of enclosed panels. It has very poor adhesion properties. It WILL fail and peel if used on surfaces other than the inside flanges in a pinch weld. It's one of the most misunderstood, and misused products in the industry. Some manufactures do not even allow it in their repair procedures at all. It works by galvanic corrosion. The zinc or copper corrodes and forms a "seal" against further corrosion, rather than breaking down like steel corrosion. When a plug weld is made on a pinch type flange the primer liquefies and then has some ability to "wick" back in around the weld. It's a "better than nothing" product. The joint still must be sealed completely after welding or it will still corrode. It's just a PART of the corrosion protection process used in modern collision That said, I use it in both modern collision and restoration, but only where its "pinched" between two pieces of steel. I prefer the copper from UPOL. I think it has less effect on the weld, than the zink. Tests I've read claim both are about the same in their "limited" corrosion protection. And Another: Tin bender is on the money, ICAR is in flux about both though as its been suggested they actually cause corrosion. There is a new product from Valveoline which you spray on the edge of the pieces of metal after welding the bare metal. It creeps in between the pieces & surrounds the weld with a polymer which blocks moisture. They have a few products in that line. When I took the class for ultra high tensile strenth steel repairs they mentioned that it may be the future type of product to replace copper/zinc weld through primers. we tried it at our shop but the manager was to cheap to purchase. Hes waiting for it to be mandated, like most everything else. LockDoc

Re: Where you all get your weld through primer these days?
Would you consider welding on angle iron that runs the length of a 1954 truck bed on either side at the bottom just above the wood planks a pinch weld? I plan on drilling holes in my angle iron every 6 inches then mimicking spot welds (aka rosettes) in those holes to the bed sides using my MIG. I plan on using weld through primer on the back of each angle iron and along that line on either bed side.

I wouldn't call that a pinch weld. If you are going to drill holes for the spots I think I would just use something like Rustoleum primer between the pieces of metal. Maybe someone else will chime in on this for more info. LockDoc

Re: Where you all get your weld through primer these days?
I got nothing for that bed repair, but I'd only recommend that anyone welding through zinc ought to be careful about fumes. I know people who have died from welding galvanized pipe. I realize that the spray zinc is probably a small problem, but that stuff is cumulative.
