metal repair

Recommended Posts

Hello, I'm new here. I have a 1973 Porsche 914. I recently had some rust issues dealt with and also a complete bare metal repaint in original colour. However while reinstalling the rear tail lights I found a "hole" in the trunk. It is along the edge of the car were a vertical surface meets the trunk floor. Right above the exhaust. It is approx 5" x 1/2" in dimension. It was buried in this thick tar-like stuff,and undercoating from the bottom. Finally the question.

Can "Lab Metal" product fix this? or should it be cut out and welded?Any info appreciated. Thanks in advance. Cheers,Dion confused.gif

i suppose you could do a repair without applying heat of any kind to the area, but your description sounds as though this may be a structural location. the only way to be truly rid of rust is removing it back to solid clean metal. given the money and effort you have invested here, i would opt to weld in a patch panel and know the repair has been done properly. otherwise this is going to nag you for as long as you own the car.

Dion: Any of these products are only a Band-Aid type of repair...If you are going to keep the car I would have a patch welded-in!!!

This type of repair just won't last...and in fact could foster more rust!!!

Thanks Brad. I do believe I will just have the gentleman who worked on the car do just as you say. It is a small piece in the trunk. It must have had water leaking into the area from the tail light. We didn't find it at first. Everything "looked" solid in the trunk. No hints of rust. I discovered it when I went to remove some of this "tar like" stuff the previous owner must have used as a seam sealer? I was preping the area for a new carpet. When I was scraping, a chunk came out revealing the hole. It is not as big an area as I first thought. I will head all suggestions. Take out a decent surrounding area and weld in a new piece of steel. Thanks guys. I am really enjoying this site.

It is certainly different than the 914 site. Cheers all,Dion
