Done opti coat for a week plus, cannot tell you this product is better then other product  as 1st year any product of coating should be  in the perfect condition, it might only degrade after a year . will input comment after a year later.

base on experience on opti coat and ceramic pro during collection of car , the difference is ceramic pro given more "wet shining look" . water repellent parts is the same since it still new. 2 year above comment on ceramic pro you can see on my previous comment .

first impression during  car collection

1)convenient part - Opti coat win - as he go to your house collect car and send back to you after coating, no need hazel to call grab car two time 

2)wet look shinning part -  ceramic pro win

3) professional of handling - opti coat win - as is the boss it self ( perhaps together with worker )  done from  A to Z, it provide more comprehensive or rather say more focus to make your car in perfect condition before coating
As i still remember when i collect my car from ceramic pro , since i not free, i delay one day to collect, during collection, my car is park out side and lot dust appear on my car, i did complaint and the they said guaranty already coating go back spray water and the dust will out easily (- which is true after i  do it at home). Just that i paid so  much , even i delay a day to collect my car and you notice i will going to collect my car, as a business point of view, you should wash and deliver to me in shinning not dust look right?
