Weld-Thru Primer Worked Amazong
I used POR-15 Weld-Thru Primer on my 1986 CJ Frame. I ground down the surface rust and previous frame coating down to metal. Then sprayed on the weld-thru primer and was able to weld my frame stiffeners on. 10/10 application and use!

Love this stuff
I’ve used POR-15 products for over 20 years and they never disappoint. The weld through primer protects my metal and allows for better welds.
