I knew there was rust on the bottom and I was going to wire brush and clean it up & paint it etc.
Now I find that it isn't just rust, as I vacuumed the insides of the battery tray, rusted metal flakes peeled off and a bit of tapping with my fingers opened up a nice hole.
Question I have is do I take to a body shop and have them cut out the section and weld a plate on or are there any diy solutions that could solve the problem of patching up the hole. I can deal with the rust but sanding priming and painting it.
When I searched the forum for similar issues there are some suggestions like finding the body part out of a salvaged Vespa cut it and weld it on this bike or using fiberglass mess and filler to patch the hole up etc.
What would be a good fix to last through winter i.e. till next April.
