Spent a lot of time on the E9 today, even though it doesn't seem like much.
Began with smoothing out the filler applied last week, using sanding blocks and #50 paper. Important thing was to establish the height at the hood cutout corner. This would establish the shape of the concave curve between the hood opening and the top of fender and how the shape progresses towards the roundel mount. Shaping the cutout at the hood opening corner took some work.
After applying a little more filler I ran the headlight buckets through the POR-15 clean and prep drill. All that black means the Metal Ready is working. I can't decide whether to leave them the way they are or weld in some patches.
Did more sanding, found more low spots, especially at the LH corner. Add more TECHNIFILL.
The contours finally began to come into focus. Spent a lot of time working out the curves at the LH corner, were multiple curve planes converge.
Eventually I reached the point where I had to paint the entire area to get a better look at the contours. Began with Evercoat #720 Acid-Etch Primer, and after a thirty minute dry time a few coats of High Build Primer. I'll start sanding that next week.
