i use HOK everyday. in my bike paint shop. webpage listed in my profile will show you alot of samples. i uses ppg or hok on everything. just read the tech sheets for each of the products or get tech book. be aware when talking candy colors some of them take 6 coats to get the color that adds to time & material cost. pearls & flakes can be added to base or clear. must put 2-3 coats straight clear on top. i have found it is best to rub out the day after clear, as it gets harder & quicker than other paints. hit it right away & you wont chase scratches as much. as far as spraying most of my jobs don't need to be rubbed out, the clear is that good, & it flows so nice.watch your wet spot jwart
