The clear is thinner on the older pins compared to Sterns so no so deep.
Plus Like Phil said has flattened out.
Take a closer picture at an angle and you will see them.
Not a problem as every machine has them regardless of what people say.
Only way I can see them is to zoom right in on a pic taken at the right angle, so I’m wrong they are there but only just even though I was looking very closely by eye and I used to do car panel work and normally see everything.
My TAF and TZ have had new thick clear coats and plenty of air balls but I’m not seeing anything like the above pic, must be the height the ball is dropping from as even the metal ramp flap is dented.
