+1 for Farecla products.
I use them every day and honestly wouldn't use anything else.
(And T-Cut is crap, I wouldn't touch it personally)
Super resin polish won't solve your problem as its just a "top coat" it has no cutting compound so the best it will do is mask it a bit temporarily.
What you are trying to do is remove some damaged clear coat that is stopping the light reflecting cleanly off the base coat colour. You need a cutting compound to do that, and a degrading compound is ideal (one that breaks down and becomes less aggressive in use, and then finally becomes a true polish to finish)
If you don't know the thickness off the clear coat (paint thickness gauge) you run the risk of going through the clear coat and that's your paintwork knackered.
Personally I would use Farecla Fine cut, with a DA Polisher. But I would measure the clear oat thickness first, as I would imagine there is a VERY small amount on a bike frame !!!!!!
