Boxer owners and stress cracks by turn signals?

Part of the reason I had my Boxer repainted was due to 2 stress cracks near the inside of the bottom of the turn signals that went to the bottom of the hood, these are right by the hood hinges, the cracks were thru the paint and layer of bondo down to the aluminum, the shop grinded out the bondo all thru the area and refinished it.

My car is almost back together, just finishing up the bumpers to have them put back on and the black trim on the rear lid being re expoxyed, all the rest of thebalck has been done. window trims etc. as I was looking at the freshly painted hood sure enough the stress cracks are starting again near the turn signals, its not due to a paint issue as they put flex additives in the paint and supposedly you can paint a vinyl seat with this stuff and sit on it and it will not crack, so they have grinded off the bondo on the front hood by the turn signals and hinges suspecting a possible crack in the aluminum somewhere but nothing, so all I can assume is just metal fatigue in the al from opening and the weight of the hood thru the years causing this area to flex each time its opened and cracking the bondo paint.

Does anyone else have stress cracks in this area or have you seen it on other Boxers?

Iam trying to figure out if this is common on Boxers or something unusual with my car, the remedy will be to reinforce this area with aluminum rods and skin and refinish it over again.


Thanks in advance

 

Thanks for the replies.

What they ended up doing today was making a special metal bond in the area with special adhesives (were the aluminum joins the metal framing on the hood )all through the inner lower turn signal areas and riveted a small reinforcement in the corners where the bondo cracked, the aluminum hood is fine underneath but must flex alot when opening the hood, the repair will be invisible and should solve the problem if it doesn't they will go to more drastic methods of reinforcing the area with small aluminum rods and covering them with additional aluminum skin, but the metal bonding repair should work.
