Can be the bonnet dismantled ? (steel frame from alu skin)

Hi all,

I would like to know if the steel frame can be separated from the aluminium skin, as the glue that hold them together is gone and the frame is getting some rust I want to stop.

There are some rivets to remove but I still have no clear if the frame can be slided out of the skin, as it seems that is "wraped around" the frame at the front end.

Thank you,

Carlos

I am just starting a rebuild and have also wondered the same thing, as the frame is only a bit rusty and the ally skin is good, I would just like to treat and repaint the whole thing........my gut feeling is that when the rivets are removed the skin will come away with a bit of persuasion..........

Hi,

I removed all the rivets, as well as the spare wheel mount. Found some galvanic corrosion in the aluminium, as the spare wheel plate is hold with steel fasteners and they touch the alu skin. Need to fix that.

Unfortunately, I got stuck with the glue. I was using the sharp paint scraper approach, but it gets jammed with the glue. Then I tried to help with the heat gun, it helps a bit... but the alu can be easily distorted.

So I will make a tool, a thin stainless steel blade with a sharp hook in one end to remove the glue, chunk by chunk. As mentioned before, a normal blade/scraper gets jammed between the frame and the skin. A different tool is needed to actually remove the glue from the equation.

Photos will follow soon.

Done. I used a 0.5 mm stainless steel plate with some cuts on it (like a homebrew saw) but the idea of a sharp paint scrapper helped with a hammer is also valid, but the alu skin might be dented from the underside if this is not done carefully.

Frame can be removed from the skin (it is a bit tricky) and restoring the glue is going to be tricky too, as the frame has to be slided into its final place, so any glue/gap filler will be oddily spreaded over the alu surface.

Suggest you get it zinc sprayed or similar - you' don't want ot be doing it twice! Also, when reassembling use some DPC or other physical barrier to prevent the galvanic corrosion next time. Maybe a super thin skim of tiger seal followed by a layer of DPC on the skin and then use tiger seal to stick the frame together.
