Don't do it!!!
Why destroy the beautiful nose of your precious baby when you could just get the 3m mask instead? I dare say it might even be cheaper...
The "Owner/Operator" and Mother Nature will ruin the finish, not the Bra. I can't tell you how many cars I see driving in the rain with them on
. That is a big no-no, Colgans bra even tells you to remove it during foul weather, reason is, sand, dirt, that the rain holds, will work its way under the bra and settle, any slight movement, or failure to wash underneath the bra will be abrasive to the finish.
Now, I researched this for about 2 months. After talking to many about this subject, I concluded two things:
A)If you go with a bra, you HAVE to remove it when it begins to rain or snow, and ONLY put it back on a FRESHLY CLEANED AND DRIED finish. The backside of Colgan bra's is a very soft material that will NOT damage your finish, but the dirt trapped within it will, thus the above summary.
B)Clear bra's ARE more expensive, and I've yet to see one over 2 years old, the one guy I did speak to that had a clear bra (3M one) said that after about 18 months, little bits of dirt began forming on the edges that just would not wash out, he ended up stripping off the clear bra.
Now, the reason I got one was because I was getting tired of seeing the little tiny sand-blast nicks in the hood line of the finish..granted we only get about 125 days of sunshine in the Pacific Northwest, I figured its going to reduce those nicks by 33% over a years time. I strictly follow the aforementioned rules above, and it gives me peace of mind. Take care of it, make sure the bra is clean, and the finish is clean, don't use it in the rain, follow those rules, and they're worth their weight in rock-chip gold!
One other advantage to Colgan bras are the stiffener shown in the pics below, they deflect any rock chips up over the car (seen it happen just the other day!) and it takes me about 30 seconds to put the bra on or take it off. (Its a "Sports Bra", not a full frontal bra)
You can get it WITH the roundel cut-out, or without it (Without roundel cut out below)
Edit: I might add, I only use it when commuting, I really dislike the looks of the bra's on cars.
