I just used the maguires kit . Comes with all the bits you need to do a great job!
Mine were off the car when it was away getting painted so I set about them!
Very good kit and delighted with the end results
The sanding pads are Velcro backed so I put mine in a drill with an attachment I bought from "geek" for £2 and it tore through the yellow haze at a very controlled rate, not to quick that you would damage the lens but quick enough you see progress quick enough, the paste cuts away nicely and the sealer is easy to use!
Kit cost £18 in Eurocar parts
