Now that I've got your attention, maybe someone can help me out.
I am going into my second season with a Colgan bra on my '90 Westy.
While it does prevent rock chips and keeps the bugs off the front, and especially out
of the A/C condenser, it presents new problems of maintenance and cleaning. The
biggest problem is sand collecting underneath around the edges. This happens everytime
I drive to San Diego on the highways through the sand dunes of Imperial Valley, where
there is almost always blowing sand and sometimes flat-out sand storms.
What I am doing now, is washing it with a mild solution of dishwashing soap while it
is still on the van, rinsing and wiping down, and then removing and draping over
something to dry while I wash the rest of the van. When it is dry, I have to vacuum
the fine sand out of the felt backing.
So, how are others cleaning and maintaining their bras. On their vans, of course.
