Hi guys i've recently bought the VXR roof spoiler and had it sprayed to match my car colour (Casablanca white). When i went to fetch it it looked nice, after about 2 weeks now, it seems like the paint is forming bubbles. I dont know if this is just down to using the wrong primer or just a bad spray job. Those of you who have done your roof spoilers, do you guys know which primer was used. And, are there any suggestions, should I take it back or just leave it as is, as its a mission to take of and fit again??
