Having lifted a damp carpet and discovered holes in the upstand panels along with horrible gungy white stuff this is my next project (i am assuming that the gungy white stuff is aluminium corrosion ... but it feels greasy, and my Id have thought it might be dry and powdery?).
Thank you for the pics and pointers as to where to buy new panels.
The rusty bolts holding the seat brackets on and the floor panel do not look like they will be fun to remove :/
