What grit do you block sand the filler with on this job?
OK...I think I see...you press really hard and work it into the holes, moving in many different directions..."shaving" off excess until the holes are filled...then you "cover coat" it with a thicker wipe from the rest of that same batch?
What grit do you block sand the filler with on this job?
Is there an old bodyman rule of thumb for filler/hardener ratio? Like...for every tablespoon of filler it take a spot of hardener the size of your pinkie fingernail?


see above 


I am having to do this outside in the front yard...do I need worry about trying to do it in the shade or in the open sunlight...temperature of the metal as I am putting on the filler?


was that all filled with something similar to the duraglass?
hard to tell from the pic, but it almost looks like All-metal filler in there...
IF you make sure it's as sandblasted as it can get, and you go for the refill, it can last surprising long.... you could probably get 10 yrs out of it before it possibly rears it's head again......
