Re: Applying weld-thru primer
ive been using the 3m weldthru ...got it from oreillys ...and it is close to 30 a can....but you don't want regular primer where you are welding...itll burn when you weld it defeating the purpose of the weldthru and make your welds look like crap....
I spray the weldthru directly on bare metal...let dry...then weld
I may not be doing it right but that's the way I do it
