Ive blacked out the front end on my car and taken some pictures of how Ive done it, personally im very happy with the result and for $30 a can (at Autobarn South Australia) it gives a lot of character to the stock bumper!
How It started off

Masked up and after afew coats

End Result, even went and blacked out above the grill where the chrome logo is (also done rear logo)

Next thing I have done is only for Sportsback models, I couldn't afford a rear diffuser or any expensive bodykits so I thought this was just as good!
Masked up

Ready to spray

After afew Coats

Finished lip, used a Stanley knife to cut around the edge for a clean finish

Very happy with the end result for $30 For all this Plastidip

Hope I have given you all some idea's and would appreciate some feedbac!!
Hope you liked what ive done, ive deffinatley enjoyed Plstidipping and 10/10 would recommend so far!
