There is not just that one person who has had a bad run with Plasti-Dip; there are plenty out there that have had bad experiences with it when they have done larger projects (entire cars, panels and more). The most common problem people have with Plasti-Dip is clearcoat; it will eat it.
Every manufacturer uses different clear coat and paint. Some people will have problems with it and others wont. You wont know until you peel it off. If it does come up, you have 2 options. Continue re-applying plasti-dip or have your car resprayed.
Prep work is everything with stuff like this. If you cut corners with it you may end up paying for it in the long term. Vinyl wrap is more expensive but it has fewer risks compared to Plasti-dip. With today you pay for having peace of mind.
When Plasti-Dip first came out it was never intended for automotive use. Its a solvent based product and will react differently to whatever material its put on. Its not designed to last either. Its good for a few months but after that depending where you live it starts to peel off. Plasti dip doesnt last as long if its exposed to snow though. Vinyl is the same, they all react differently to snow and high heat. High heat they can fade and crack, in rare circumstances they bake onto their surface.
There are new alternatives to plasti-dip that have come out to work around Plasti-dips drawbacks but some arent available in the US.
