Ok, I don't understand the problem with painting bricks, but it seems they
exist. Even TT is nervous about painting them.
As I understand it, there are two problems. First, anything but a
water-based basecoat will cause the acrylic to deteriorate and the crackle
effect begins. Second, there is a claim of the body panels flexing, causing
the paint to crack and separate from the acrylic.
Now the first one I understand, but after owning a fiero with extremely
flexible "enduraflex" panels that actually flex under finger pressure, with
absolutely no signs of paint problems for many years using flexible
coatings, the second problem should not exist. Personally, after lots of
painting experience on many different substrate materials and many different
types of coatings, the type of cracking and separation on the B cars I've
seen appears to be very similar to problems caused by a lack of adhesion
between the substrate and coating used. This would suggest that it is not
flexing that is the problem, but adhesion, adhesion, adhesion. I'm very
interested in others' experiences and hypotheses.
