Why is my hood paint cracking like this?, Any ideas on how to prevent this after next respray? Options

[oakdalecurtis]

The front area of the hood on my "76 914 was professionally spot resprayed five or six years ago due to cracks in the paint. That painter retired and is no longer in business to return to. Cracks in the paint have again slowly and continually opened up, and the cracks seem to be in a line parallel to the front edge of the hood. Could the hood be flexing while driving and causing this? The underside of the hood nor the front of the car show any sign of previous accident damage. I am going to sand this area down soon and have it resprayed by another paint shop. Should I make sure that the next shop does something different during the paint process that might prevent this from happening again? Has anyone else had cracking like this in their hood? Any advice appreciated.

Its most likely cracked body filler. Sand it down to metal and respray it. Take a weak magnet and see if it sticks. They probably put body filler on it when they shouldnt have. I can take a look at it if you want sometime.

As usual, you nailed it Andy (and Tom and ToolGuy, thanks). A weak magnet sticks everywhere but where the cracked area is, must be bondo'd. I now noticed that the hood badge was originally in a lower location, (see pic below) and was moved to its current spot and the old holes were filled with bondo by the PO. That's the source of the repair, not an accident. I read somewhere that holes that are bondo'd like that will eventually crack through the paint, so maybe I should have them welded closed on the next repair? Andy, I would be honored to bring the car to you when you have a little time just to give it a brief once over with your expert eye and experience. I am retired and pretty flexible time wise, so it's up to you what might work best with your schedule. You have my email if you would like to reach me, bjic, oakdalecurtis@aol.com,
Thanks again, cwl
