Seymour 20-1675 PBE Professional Primer, Self Etching/Weld Through Gray

worked very well so far, sprayed nice, stuck well to sanded and prepped surface. Welded through nicely (as nicely as can be expected) should hold up well. Dried faster than expected, and kept work flow going.

This stuff may be a little bit pricey, but it works very well. Welds fall asleep and prevents rust along while keeping a good finish. Can’t really complain.

This is my go to primer for everything. Quality is there and covers real well. Can be used without cleaning the surface after priming if you’re going to weld. Definitely tough stuff, painted outside A/C grate and left it unpainted for quite a few years and stopped rust in its place.

Easy arc and good puddle for MIG and stick. Worked OK on thin (<1.2mm) spot welding. Forms slack inclusion on >1.2mm spot welds, spots come apart. Burns out when you weld, you'd need to clean and reapply after your weld is done.

Works great! Great quality cans.

Sprays good. Weld is good

Seems to be a good quality product

Work great

I had never used weld through primer before (didn't know it existed really!) and I was very pleased with the result. Sprays out like any other primer/paint and dries very fast so you don't have to wait long before welding. Welding through this primer doesn't cause expensive smoke or spatter in fact the resulting welds are quite clean, highly recommend.

Great coverage and sprayed well

Great primer. Expensive, but the finish is perfect and it dries fast.

This works excellent

Dries super fast, goes on easy great consistency and spray area.
