Cary:
1 quart of POR15 will give you enough for 2 coats and enough
left over to do the prop shaft and some suspension pieces.
The rust is because powder coating gets thin wherever there is a
discontinuity in the metal surface such as near a bolt hole, or on the
inside of corners and frame members. This is because the net electric
field in those areas is nearly zero, so there is no electrostatic charge
to attract and retain the powder. This is why brushing on something like
POR 15 is superior to powder coating. Nothing beats powder coating for a
nice appearance however - so if you want the best looks with good rust
protection, powder coat. If you want the best possible rust protection
with decent appearance, POR15.

Subject: Frame Coatings
I have a frame that has been sandblasted and powdercoated. The frame
was
stored outdoors for about five years. It shows some minor surface rust
on
some of the corners, and also on some of the bolt holes. None of the
rust
is major and most of it just wipes off with a shop towel. I was
wondering
just how durable powdercoating is, and if it is ok to use this frame the
way
it is under my body, or should I sandblast it and recoat with POR15?
Also,
I believe I read that it takes about one quart of POR15 to coat the TR6
frame. Is this correct? Thank you very much for your help!
