Porsche paint is relativly easy to work with.
I have done 3 porsches this past 2 weeks, and all have been pretty easy to make look real real nice! I would recomend washing with car wash soap, not dawn, then claying during the rinse stage, then rinsing and drying. There really is no need to wash again. I have been doing it this way for about a year, and it works just fine! Then if you are going to use BF as the LSP, i would recomend sticking with it through the whole process BF polish, then BF sealant. You will be happy with the results on the blue i think!
After Corey convinced me to use BF on the 350Z, i compared it in my mind to Wolfgang, and felt they were on the same plane. Wolfgang is a little deeper, BF is slicker. Either way, i think that the BF will give you a decent finish
GOOD LUCK
