I also don't want to hi-jack a build thread but I feel like I have enough experience with plastidip to share my 2 cents. I've used the DYC stuff to do 7 full cars. I've also done numerous sets of wheels, hoods, grilles, etc. with rattle cans.
Will it last forever? No.
Will it look like a professional paint job? No.
Can you successfully do wheels and have it look good for a few years? Yes.
It's also been stated numerous times that the prep work makes all of the difference and that's very true. Another thing that people don't realize is that you have to put it on really thick in order for it to peel off nicely. We're talking like 5-6 thick coats. The other thing to remember is that the longer it's on the harder it is to come off. If it's been on for a long time and you can't get it to peel, the best bet is to spray a couple new coats over it as a peel coat. They also make products to help protect the finish if you're worried about it.
We dipped my wife's car and it sat outside 24/7, summer, winter, you name it for 5 years and it barely even faded. As long as you take care of the dip, it will last a long time. I plastidipped wheels that took about 2 years of daily driving before needing a quick fresh coat to look new again. I've also peeled entire cars and it was a nightmare and you'll never get it out of all of the body lines and gaps. As for the Goblin you wouldn't have to worry about that since it's just a couple of panels that you can spray off the car.
It is definitely not meant for the folks that want a show car finish or just want everything to look perfect but if it's just a weekend cruiser or track car plastidip will hold up very well to the abuse.
The different colors and finishes you can do with plastidip for such little money is unmatched by anything. Vinyl wraps have a lot of options but are expensive and limited. You don't even have to peel the plastidip off before applying a new color. 1 or 2 coats over the other color and you have a brand new color. The thicker it is the easier it is to peel. You can also paint whatever you want right on top of it. That's what we did with my hood. I dipped it red and then we painted the sides silver so most people assume it's a sheet metal hood that I painted the center red. There's no way I'd paint on vinyl, it's too expensive to play around with.
Almost everything you can do whether it's paint, plastidip, vinyl, powder coat, etc. is a good option as long as you understand what you're working with.
Sorry for the long post.
