Looked in to smoothing mine, it will be a right pain. That marcel as smoothed the two together and as a lovley crack in it, it would be best to keep them seperate to allow movement between the two if you hit it when parking against a curb etc.

Could it possibly be done with a better/ stronger finish if it was plastic welded?

Thats Marcel's car and it has been smoothed. Looking to do the same with my replacement one when the body work is done eventually.

Is marcel on here? I'd love to see some more pics of this car 

It will still crack the paint as it will be the weakest point still. Best is to smooth the original bumper and the gt lip seperate and just clip them together as normal. You will still get cracks over time, never know any bumper that has been smoothed not to crack over time due to heat, cold and just bumping it (mainly lowered cars).

For those still interested/ following; I've heard back from my *ahem, dealer and he can supply them for £163 and some pennies inclusive of VAT. I think there would need to be a minimum of 10 to get this deal. They are in short supply in the UK at the moment. In fact the stock in the UK is 0. They can however be sourced from Germany. Not sure what the P&P costs on top would be to us once they are in the UK though. So, to sum up; £163 +P&P from within the UK.

im gonna guess this has fallen through?
