sure thats great and all as long as you never plan on traveling on gravel roads.... because the first rock that chips your bumper will crack the shit out of the paint. look at all those chevy corsica's or whatever they are, they never used adhesion promoter or flex agent either and those cars all look like ass because the paint chips/seperates after a year or two.
the only way i would do this is if it was just a winter beater. otherwise your just wasting material and time going through the motions whilest cutting corners.
ultimately its up to you, its your car. if you want it to last you'll do it the right way. if you dont care and are just slapping some paint on it go buy some tremclad and a bunch of rollers......
Which was why I mentioned that 'Other may disagree with me', fully aware that someone would find issue with the approach. The basis for that statement is that the bumpers, at least for the CRX, are not plastic, or at least not plastic in the sense that the aftermarket fenders and header panel are plastic (which I did use adhesion promoter on). I was told the bumpers were urethane based. But, depending on the chemical make up of the primer that is used determines how it will chemically bond with the material its applied to, and that it turn leads one to use an adhesion promoter. As far as flex is concerned I was informed, by several different sources, that the part that is being painted needs flex if the part isn't rigid. On the CRX, not sure about the Civic, the only piece that fits this would we the 86/87 Si spoiler.
Do I do this professionally...no, but I verify things from different sources and make a decision based on the findings.
