Upgrading Grille

[Jonoiles1231]

Hi, new to all things Audi!

Just bought a 2015 A3 and I’m looking at changing the front grille to this... https://www.ebay.co.uk/itm/AUDI-A3-S3-S-LINE-RS3-STYLE-GLOSS-BLACK-GRILLE-8V-2013-2016/183708773242?fits=Car+Make%3AAudi|Model%3AA3|Cars+Type%3AS3+quattro&hash=item2ac5e56b7a:g:~yAAAOSwNRJceEtN

and need some advice how how easy it is to change it at home with basic tools? Have read that taking the bumper off is advisable.

I want to change the chrome frame/rings and have seen someone use plasti-dip or something similar. This would obviously be a cheaper option but will it be as effective?

Any advice would be much appreciated. 

Thanks
