I've ordered a Wardlow custom bra and did a trial fitting, after which I sent it back for some tweaking. Mine is their first classic style Speedster bra. I can't say enough about how good they've been to deal with.
The problems normally associated with bras can be avoided if you follow a few simple rules:
1. Make sure both the bra and the car are clean before putting one on the other. This is to prevent grit between them from damaging the paint.
2. Don't leave a wet bra on the car any longer than you have to. This will avoid clouding of the paint due to trapped moisture.
3. Make sure the bra is tight and secure to prevent flapping.
I plan to use mine only for highway driving, and the only time I'm likely to drive in the rain is on the Carlisle trip. I'll post pics when I get the bra back and mounted.
