Yep that was me that done the Mini Cooper S. Matte black with blaze green rims. It's very easy to work with!
It's the woman's car, she wanted to vynil wrap it but at the cost of wrapping it v.s the cost of dipping it we decided to dip the car.
On the plus side of dip you can peal it off no worries (providing you do 4 or more coats) I have no I dea how easy it is to peal off vynil or what it does to your factory paint underneath.
As far as cleaning/washing goes, you just wash as normal. The day after painting I washed it with a bucket of hot water and car wash stuff with a sponge and scrubbed at it and it didn't budge. I got the high pressure hose onto it too and got about a inch or two away from the nossle and it was fine. We drove to Sydney from Melbourne in it too a few days later. Got plenty of looks (I think it was the blaze green rims) and a few thumbs up. There was no stone chips just bugs! Lots of bugs!!
The plasti dip drys as a rubber coating and so it's got a rubber texture to it and its got that feeling where you just want to pick at it.
I seriously recommend it if you're on a budget. Or want a quick fix from paint fade or even do your whole car if you put a multi colored body kit on.
I plan on dipping my bonnet/boot maybe roof on my 32R in the near future.
I'm not usually on here much but if anyone wants advice or see a few progress pics of the mini just PM me your mobile number and ill SMS them to you.
Cheers,
JUSTIN.
