Alternative coating  recently coated my para 18/9 the detail was surperb  this looks like factory finish.He  also coated an STI , AK for me they both look factory finishes. My experience with him has been great the turn around time is wonderful. He tuned my trigger and know it has less travel. The amazing part of my experience is the attention to the detail.  I would recommend Alternative coating to any one he is honest, trustworthy,also customer satisfaction is always high on his list.
