Posted by: ruby914 Jun 9 2012, 12:41 PM
I will start body work on my hoods soon and wonder what is the best way to address this issue.
The sub structure to hood panel bonds, on both of my cars front hoods, have visibly degraded.
Rear hoods are not bad.
The one shown has a lot of flex and has lost 80% of the bond.
There are some small dents I need to work out then I figure I should rebond the sub structure before final prep for paint.
I am thinking, let it cure with a good rubber seal and the hood shut to take any rack out.
Too rigid a bond and I would be concerned about a mark off on the top, to soft and it will flex and not hold up...
Any suggestions on bonding agent or proven method?

Sorry but I don't have any advice on the repair. It seems there are a lot of hoods available. People who part out cars have an abundance of them. For some reason, they are not big sellers. Think about a replacement.

I'm slowly working through RiqueMar's build thread, and just passed this point where he decided to add spot welds to the very area you're talking about: http://www.914world.com/bbs2/index.php?showtopic=88955&st=80#
There's a brief mention of a ripple afterwards, then the car is painted. Not clear to me if he had an issue caused by the spot welds or not...

Wurth its weight in gold. It won't suck the outer skin down as it cures leaving low spots. When the Miata's came out they had a bond issue on the aluminum hoods and this is what the factory recommended. Thats how I found this.

These look like good products.
Expands 10x, sounds a little like Garilla glue but cures faster, I will have to be careful working with it.
Thanks Guys

havent seen one hood yet that is bonded fully to the frame, and I have seen many. maybe they never were bonded that well.
most of the not-bonded hoods still fit well, and are not having bond related cosmetic issues on the outside.
