I ordered a silver lens from TrooperBay at the same time (for the Shadow Scout), and had tried putting that in behind...It improves things, but is perhaps too dark.
Ordered several pairs of cheap red and mirrored lens ski goggles that are flexible, we'll see how that works out...
Completed the bondo, put on two coats of primer... and then the bondo raised in 3 small and 1 large chip and flaked off (at really weird places on the top and back ridge of the crown, where I haven't worked for days...) It's been -20 to -24ish C here and I have an uninsulated garage, so I imagine that was temperature flux (wet sanding indoors and then painting it outdoors too quickly... (?)
I think I didn't sand enough of the shiny layer off the helmet around the trapezoids on the back, as the primer dried but left a weird lightning bolts / 'crows' feet' pattern... sanded it off and will move to acetone/bondo paint, I think.
