i agree with you to an extent, i think its tacky if you plastidip every freaking thing on your car, especially the rims.
In my case Ive used it to black out my gas cap/side scuttles where paint just wouldnt look right IMO. My rims are a unique finish where its not quite matte nor not quite glossy. The plastidip finish matches it perfectly.
I also think it has an OEM look to it, especially if you use it to black out your emblems. If done right its very tasteful, if over done you went plastidip crazy then its time you sell your car and ride a bike
that looks fantastic! now see, thats tastefull
