Technical Filling welds the right way

First time welding in panels. They came out great but I am unsure what is the next step. Grind down and epoxy prime then fill? Or fill the bigger issues (something that needs more than a very thin layer) and epoxy prime then do the finish touches again with filler.

 

Need pics.
Usually they are ground then hammer and dollied to remove stress from the welding process.
From there it’s up to you.

 

grind
epoxy primer
body filler
reprime
sand and paint

 

Grind,fill, epoxy here...
I know people that like to epoxy an fill over... To me it's just another"bull's eye" in the final scheme of things... Results may vary... 38 yrs. In the business

 

Grind, hammer and dolly, epoxy prime, filler, sand, high build, sand and paint shiny.

 

Take your time grinding so you don't get the metal hot and warp it........

 

I have found that when you hammer and dolly a mig weld it often cracks. I would like to hammer the weld when it is still red but I don't have 3 hands. So far, I weld carefully to get good penetration with little build up on top and then grind the weld down. I wish I could hammer and dolly it down first but again I am afraid of cracking the weld.

 

Fill the larger holes with..."weld".
I'm doing that now. I put two hoods together to make up a cowl induction hood. I'm doing my best to finish the whole weld, about 5'+ of weld with NO plastic filler.
My semi-finished pictures are too large. Will have to shrink one tomorrow.

I tend to use Allmetal or Kitty Hair over the welds to fill after grinding down the welds. Those products are supposedly water proof so if I miss anything I'm hoping I'll be ok. Epoxy and then the rest of the dance...
