Only an observation and a few questions as well? what speeds were you using in each process?Alot of times just increasing speed of PC will help out(not all the time)sometimes more aggressive product is needed other times more aggressive pad is all that is needed, all this comes with experience and even with experience can run into to some problems, never give up till you are satisfied or you have spent to much time on one process then its either time to move up to circular buffer of leave it to professional or leave it and live with it. Now on to observation after you did all those steps, you now had three steps there you might have gotten same results from first product with the three steps also, allot of mistakes hide under several coats of sealant/wax and takes several steps with PC to get down there,where as circular gets there much faster but can make mistakes costing BIG BUCKS to fix.Just take your time and try different products and when you find something you like stick with it till you read something better LOL.
