Since AGO doesn't allow outside-links to products that are similarly sold on their site
(in this case: DeFelsko EPTGs)...
I'll just say that for a more accurate EPTG than the one you posted; one that costs just a little over your $200 limit:
•HighLine Meter Paint Thickness Gauge I (HLM-PTG I); or:
•HighLine Meter Paint Thickness Gauge II (HLM-PTG II)
•I've got a couple of questions, though:
-How thick was the original factory-sprayed CC paint?
-How much of the original CC paint has already been removed by the other Detailer?
-How much more of this CC paint can you, now, safely remove without affecting its integrity, or that of its UV absorbers/inhibitors?
Bob
Owner isn't sure of OEM CC sprayed or how much CC the previous Detailer removed

Thats the biggest reason I desperately need an accurate PTG with-in my budget:xyxthumbs:
I'm using the below description for my guideline and know my micron margin in most likely slim.
Paint Thickness by Vehicle Mfg
• German and Japanese cars: 4-5 Mils
• With the exception of: Lexus-White and Tan: 5-7 Mils,
• Lexus- Black and Silver: 4.5-6 Mils
• BMW: Silver: 6-7 Mils
• FORD: Approx. 5.5-7 Mils
• GM Cars and Trucks: Approx. 4.5-6.0 Mils, Jimmy’s and Blazers: approx 7 Mils
• Chrysler: Approx. 5.5-7 Mils (Note Sebring hoods are fibreglass)
• Dodge Cars: Similar to Chrysler Dodge Trucks and newer Ram Pick-ups: Cab approx. Mils and the boxes approx 9 Mils
• Jaguar: approx. 6-7.5 Mils (but they tend to vary)
• Jeep Grand Cherokee: These read approx. 6-8 Mils, Wranglers: approx. 4.5-5.5 Mils
Thank you for all your help and advice!
