I wish that Admiral had a chief engineer that would carry out the visits and had an interest in customer satisfaction! In my case they sent a a fella from a firm called Banwells that started telling me it was stone chip damage as he was climbing out of his car before he even looked at it. He spent very little time looking at the peeling paint, in fact when I pointed out I can peel the clear coat off he said yes that's because moisture has penetrated between the clear and base coat, hee didn't try it himself. He was more interested in noting the mileage, tyre tread depths, chassis number and taking photos of the front, roof etc for his report to send to Admiral together with his bill.
One of the paint companies that I have talked to suggests that the best definitive way to determine paint adhesion performance is to carry out a cross hatch test where you use a stanley knife to score the paint in a cross hatch pattern, and then apply sellotape and rip it off to see what is removed: clear coat and or base coat. The trouble is that he suggests I should also carry out the same test on the "factory painted front bumper" for a direct comparison. Sort of double or quits, then requiring rectification at both ends of the car! It could make a good post though.
