Go to your local auto paint supplier rather than DIY store.
I needed something to strip paint off alloy Land Rover panels but DIY stuff didn't touch the base coat. The proper automotive stripped did the job without a problem. However it was £25 for 5 litres. As always it's a case of getting what you pay for. Cheap will probably mean not as effective as dearer and you could end up using a lot more so in the end a lot more work for nil saving !
