Jim:
I know you stripped it & reshot the frame. Did you try to re-powder over the orange before you stripped? I ask, as I am doing some Ford model T spoke rims using the Caswell "vanilla" powder & the samething (orange in spots) happened to me. I was going to try to reshoot the powder over the orange & then cure at a lower temp?
Thought I would ask your results first.
