my bmw 320i has a lot of swirl marks everywhere, i like the idea of fixing that myself and considering getting a das6 pro, but im wondering what the learning curve is like?

i can watch some youtube vids and go from there, but also wondering, from anyone that started off new to this, is there any value to buying something like a rear door or boot lid from a scrap yard and experimenting on that first, and then when im more comfortable moving to the bmw, or is it not actually that difficult a proces and that wouldnt be neccessary?

thanks!
