Got my materials.
The top edge of the bumper lines up to the hood by adjusting how it is sandwiched between two metal frames.
My idea is to adjust this the way I want it, before filling the depressions, and than not messing with these frames after (leave it all assembled).
Did a quick block sand of the old primer to see how bad the dips are.
Considered applying heat to the high (or Low) spots to get closer to flat before skimming the filler, but I figure it took 20 years to deform and it's probably as stabile as its going to get. If I try to heat form it, it might move back the way it is now over time.
Removed all the old primer and wiped everything down with alcohol.
Skimmed the whole surface with the Poly Flex.
Wet sanded the first coat till I hit plastic.
Going to skim coat and sand once more before I spray on a guide coat.
I can see it's going to take a few rounds to build up the low spots, but I'm trying to put the filler on in thin coats.
And I have to get up off the floor with this, my knees are killing me.

But the bumper is so flexible it bends and collapsed on them.
I want it to sit as flat as possible while I block sand.
Need to buy a big piece of plywood to make a flat supporting surface up on the horses.
The Poly Flex was a little gummy sanding dry at first (a sticky skin on top), but I found it sanded easy 180 wet.
But it's good stuff, feathered right into the urethane nice.
