Understanding PTG readings?

**parttimer** · 05-05-2014, 08:24 PM

What is a "healthy" coating of paint? I got my unit in the mail and decided to test it on my two vehicles in the garage tonight. Subject #1 is a 2013 Ram 1500, deep cherry in color. Using the mils setting I saw a range of 7-9 mils. I then tested it on my 2012 Chrysler 300 in black. Those readings were between 4-6 mils. Switching to microns the RAM saw 184-244 and the 300 was 98-124. From what I have seen 2-3 mils is good? I have polished the 300 a few times but I couldn't believe the truck was almost twice as thick.

From what I learned anything above 6 mils is healthy paint anything lower than six take caution

Which PTG are you using?

What are the measurements in the door jambs?

It was suggested to use the door jamb readings as a base number since they don't receive clear coat...

Jambs don't get clear coat? I thought the clear is what gave the shine. The paint itself is not glossy. My jambs are very glossy.

My suggestion would be to get a polish or paint cleaner and rub the door jam(after cleaning it) to see if any theirs any paint transfer cause some door jams are clear coated while other are not....just my thoughts

I personally don't mess with my door jambs. When I first got my PTG, my readings of the door jamb area are significantly lower then all the readings on the rest of the car. Maybe its a one passover of cc who knows - at least on my car. But to put the mind at ease, next time I polish, I will check the door jambs.

Sorry OP if I shared misleading info. Dam it thats twice now in a week lol

Jambs don't receive *as much* clear as the main body panels. So if you measure the jambs that will give you a general "baseline" reading to work off of as a "too thin to polish" measurement for the rest of the car.
