Valid questions.
I had a plan of various projects I wanted to do so removing the bumper was part of a bigger scheme. It allowed me to remove the stock horn visible in the above picture and fit this pair of FIAMM twin tone horns that I bought off Amazon;
I also wanted to spray Tetroseal clear wax as we have a lot of salt on our UK roads;
.....and this is underneath;
I removed the rear wheel arch liners and treated the fuel filler as this is a common problem for it to corrode and is usually very expensive;
I also took the opportunity to fit front and rear mudflaps. I will copy the instructions and add some photos at some stage but while they were not the easiest ones I’ve ever fitted, the are the best fitting.
