@Sean d has advised replacing it as he thinks it's an old repair that's gone bad.What about your FUBAR rear bumper?
I used the Autofinese sealant then just coated the swissvax shield on top. It should hold up untill we do it one more time to remove the rotor marks. The depths are shocking. I would of expected around 160 to 280 microns with it being painted but in a lot of places we were getting 380 to 420 microns which in away tells me it has probably been painted twice since manufacture or the last respray was that shocking they just kept applying it to hide the bad areasGreat results Bill and you seem to have found the cause of the problem.
Good paint thickness but as you said it's been painted so would be nice to know top coat thickness...
Looking loads better than it was, Are you putting a sealant on it after or Shield.?
Well done both of you....It was win or bust really and it looks like you are winning....
I reckon it will be around 40 to 60 hours work in total to get it right. We spent 6 hours on the bonnet but know we need to spend at least the same again before it is right. Hence why i got Dave to do as much as possible to get him confident with the rotary so he can do it at his leisure over the winter months.When you tell people not in the know how long you have spent on a panel they look at you gone out lol..
Great that you're enjoying it too Bill...Satisfaction in what you are doing and the difference it makes is all worth it.
Enjoy your beers.
