Should I fill with JB weld and then grind it down?

Or should I grind the seams first and then JB weld?

Or just coat with JB weld and leave it the way it is?

Thanks in advance

I would coat it with JB weld until you have a nice smooth surface, then paint everything with a heavy coat of paint.

Fresh coat of JB weld and new paint


Ground the seams and other hot spots and three coats of header paint


Need to clean up a little paint that got around my mask job. Then just need to swap with the set that is on the truck

Hanibel, that's nice work. Purple intake manifold = better driveability, performance, and more (s)miles per gallon. That's a scientific fact!
