After getting frustrated from looking after an mtech rear bumper, and after someone bumped into my rear bumper I decided to give my artistic background a try :wink:
the ingredients:
1 x black matt spray
1 x ultra fine sanding paper (p1000 and above will do just fine)
1 x Pressure sensitive adhesive tape (masking tape).
1 x thinner
1 x old newspaper
1. mark the "mtech lip" using the adhesive tape and cover the rest of the bumper with paper/newspaper
I used the center bumper trim as a reference for how wide it will be.
2. use the sanding paper on the bordered area.
3. clean the bordered area using the thinner and a clean rag.
4. spray the area slightly until getting a nice even black surface.
