Respray, Clearcoat Crack
Morning everyone.
I know that I may get some different opinions on this, but what I am really looking for is it something that should not happen, or is it something that may happen.
I had my car sprayed, not a full paint, just a respray, by a very reputable company in my area.
It has been about a month and I see two small areas that have a crack in the clear, about 1" long.
The first may be my fault, I was working on that side of the car and leaning over on the fender and that is where I see the crack.
The second is a fine crack in the clear, about 1" long, on the nose.
Any insight would be very much appreciated.
Thank you,
Eric

you need to make the nose solid on the rad support-bumper mount-horse shoe or air tank before paint. the headlight support is attached to a piece of sheet metal that is riveted to a glass inner fender that may be cracked and sagging or just weak between there and the rad support it mounts to. which can also be rusted on the bottom and letting the nose droop even if everything else is good. if the front is not supported the nose will show cracks.

You say a crack on the nose...Are you speaking of a crack in the paint on the fiberglass front end OR on the urethane front bumper? If the urethane front bumper, does your 73 have the original front bumper?
OR was it replaced with a urethane NOS piece or something else ?
If it is urethane was the bumper stripped? Primed with spies hecker flex primer and then flex agent in the clear?
The more paint on a flexible bumper the more likely it is to crack if it is flexed.
As an aside I have painted corvettes which people did not want taken down to bare fiberglass. In those cases I have stated on paper at the outset I would in no way warrant against stress cracks, lifting of paint from layers under what I applied etc etc as I have no idea what lies under the current paint.
