Paint removal

At sometime in my TF160 life it has had a bump, I'm fairly sure that it was a front offside as the bonnet wing gap is uneven and the front bumper has been resprayed to match the car. Problem is that it has been applied either too thick or without the plasticiser or inadequate preparation of the original silver paint. I suspect a mixture of all three.
The end result is that the new paint has cracked and crazed.
What's the best way of removing the paint back to bare?
I intend to remove the wing and the ask a paint shop to colour match and repaint the bumper.

In all honesty you may be better searching eBay for good replacements.... at least the paint is likely to have aged the same as the rest of the car. Plus it's probably cheaper.

I find spilling brake fluid on paint seems to remove it :oops:
