Good Afternoon, So after pranging my Frogmire (mk1 mx5), Iv'e had to source a new front bumper which I got for a steal at £25! My Car is BRG and the bumnper is black which isnt a issue as ill be sanding this down and smoothing before having it painted. I got most sthings assorted fine...

im going to be doing some filler work on my car & wanted to know whats the best product to use & where to get it from for best price.
