The price range using:
Regular products 250k
PPG products 350k
Sikkins products 400k
Just two major differences
1. The finishing
2. Durability
The finishing when a regular products are been used is not bad, buh it doesn't give that factory look.
It looks great, anyone can actually admire the job.
Buh when a higher end product are used, it takes a car paint enthusiast or some one in the field to know it wasn't a factory paint.
Then the durability, regular products doesn't last more than 1-2yrs. You will be needing to get it painted again after a year or two.
Buh higher end product last longer.
