Hi,
Thought about plasti-dipping my front end the same as you have. Looking online though it appears it can come out quite "mottled"/"bumpy" wiould prefer a satin smooth finish personally.
Do you think the pics I've seen are just ill prepped or spraying too thick/close?
It wasnt totally smooth but close enough. Like mentioned above, thin coats and this will get it as smooth as possible.
I no longer have the car any more and have since got a FL Cupra which as the part next to the number plate done in a GLOSS black.
I want to do the lip again but PlastiDip wont do the job this time

as it will come out satin Black / Grey type colour.
So would have to spray paint / Vinyl it this time. When I can be bothered lol.
