>Dear Van's,
>
>I am stripping all of the steel parts on my RV-8 to have them re-powder coated
in a textured black to match the rest of my interior. While stripping, I have
noticed a couple of things regarding factory powder coating. Perhaps the most
disturbing was the high build up rust under parts in certain areas, primarily
the ones made from the 4130 plate (see attached pictures). This will eventually
cause the powder to flake off.
>
>The other issue is the distinct lack of surface prep on all steel parts! On every
single steel part that I have stripped, there is no surface preparation such
as scuffing and/or phosphating. All of my steel parts will be undergoing
these steps prior to powder coating for the absolute best possible protection
from future rust break through. Additionally, the adhesion of the powder coat
is significantly better with these additional surface preparations. The cost
differential is minimal, since high-end coaters usually do these steps by default.
>
>Many builders faced with changing the color of their steel parts will simply choose
to paint or powder coat over the top of the factory powder coating. This
will eventually lead to a less-than-satisfactory result for the reasons outlined
above.
