Adam:
The two coils I coated both have the Behr Super Build 50 used on them. I
have had very good luck with this product, but I did apply it while the
secondary was rotated by a motor and gear reduction drive. Several other
list members used it and I believe one person mentioned heavy runs when the
secondary was coated and not kept continuously rotating. I let mine rotate
non-stop overnight and they ended up looking very good. I also recall that
Chip cautioned us that the product will "crack" if left out in the cold.
Hope this helps you make a choice. I bought an extra pack of the material
when someone indicated it was being discontinued--I hope that is not
correct, since I really found it to do a good job.
