I would try to clean them with car wash soap and a very soft detail brush. The paint on those covers a very thin. It may take a couple of rounds of cleaning. If that doesn't do it try APC 10:1. Do not wax them use a quality spray sealant like Wolfgang deep gloss spritz.
You can use it without a wax it is a spray on silica sealant. You can top with wax if you wish but I think it looks good on its own. This is the only pic I have of just a wash and hydro 2.
Carpro hydro 2. It doesn't last as long but super easy to use. Also Sonax has a new wheel product

Can't wait to get the revision. Me and the boy went and did some pulls on 377. He was just grinning and said "Dad your car sounds like a race car lol"

Finally had a chance to data log my car. Installed my side splitters and fooked up my mirror hitting my work bench while pulling into the garage.

I installed mine Saturday. The 93 tune is awesome. The cam tune sounds great but my car stalls just about every time I come to a stop lol. Do you have this issue?
Thanks for the response. I went through the signals and there is nothing that says AFR. I would like to monitor knock but it's not there either. I just went and checked my Firmware and it needs to be updated. This might be the issue.
How do I monitor AFR? I was told there should be an option but I can not find it? Probably user error but I can't figure it out. Also the tune seems to be on point but should I data log just for piece of mind?
