I had a hunch that SRP would do well. It's what i use a few times a year, and it works great and smells lovely to boot :D
 
i always found if you mix 2 parts t-cut with 3 parts super resien polish and a splash of life shine works a treat stole this method from the valeting team at gilders the local vw dealer as i went to school with them and there cars are the cleanest in town by far

but i still like going from rubing compond,t-cut,colour back,mer,supper resien,wax when i get a bad car in need of tlc all by hand its a bit over the top but i got asked if i had a respray or was it just a diffrent car
 
Not surpised at all by the results... SRP has always been a good product for filling swirls and scratches. Its light abbrasives bring a decent level of gloss into the paint but its the fillers that do most of the work of reducing / hiding the swirls etc.

Nice test and write up by Dave :thumbup:
