What I am doing is replacing the front section of the frame, not just the front extension, its a very large piece including the extension, the shock towers, and even more. I had to cut off the old section and weld the new section on -but obviously there will be lots of stress on it. In order to compensate for the stress on the now weakend frame due to it being cut, I will need to plate to provide and exceed the needed stregnth in order for my now 2 sectioned frame not to break. I know that usually the whole frame would be replaced, but with my skills and experience I believe I can get away with this, and where I have the 2 secions meeting-with the required plating it will hold up just find and last many more years to come. I have been a mechanic for too long and also have been doing classic car restoration for many years so the welding is not a problem at all-I just wasn't sure about how the inside of the plating would react to a long period of time after the work is all finished. To tell you the truth, any work requiring steel plating (not just frame) that I have done was vehicles for my boss bought from auctions with all kinds of damage and after refurbishing are sold- so I never get to see what eventually happens over time. The DeLorean I own now will be with me until I die (unless it get crashed god forbid), it is a car I feel that I can never sell. I just need the frame to last a few years so I can get money together for a stainless frame. I will soon be finished with the frame and will provide the pitures to show you the different stages of this interesting repair. Lastly, will coating the frame with POR-15 seal against moiture-and how is it compared to the epoxy? I believe I have a few cans of gray sitting on my self along with metal-ready but I have never used it thats why I am not sure of the results.
