Where you all get your weld through primer these days?

[Jrainman]

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 .
