What is the name of the product you use for protection ?

I can't remember & I am away until the weekend. I'll check & let you know when I get back.

This is the stuff I use(d), where are you based? I have 2 of these - one unused as it goes a long way!

Seems like a great solution to me. When I first saw inside my wings, I couldn't believe that water was purposefully routed through an inaccessible, poorly painted, closed box. I expected a solution similar to what you have constructed. Other crazy design details are holes in the front vertical surface of the outriggers, perfect for filling the outriggers with sand, which is kept damp, so rotting the floors, doors that allow water to flow internally down to the seam at the bottom, rotting the bottom of the doors, unfilled spot welded joints between inner and outer wings, rotting the wheel arches and cills, and chrome trim strips wilth sharp fixing clips that scrap the paint off the steel bodywork and hold water to facilitate the resulting rust. All brilliant... if you want your cars to rust away in 10 years!

All power to anyone who find proper solutions.

Another problem area I have altered is the rear section floor pan, there is no lip on it like the front one, and so while there is very little rust on the front outer floor area where it is spot welded to the sill, because the lip makes it more difficult for water to get up into that sill/floor area, the rear section has no lip so was rotting away as the water gets up into that join and stays there, and also rotting the sill, I know it was from there and not inside the sill because of the pitmarks, non on the inside, all on the outside where the floor joins.

So I replaced the rotted sill area, and when I made up the repair section for the floor, I have put a lip on it.

I am determined to find a solution for as many of these badly designed area's as I possibly can.

I have welded the front of the front outrigger closed too as water clearly sprays from the wheels straight through the gap into the outrigger, will also deal with any of the holes that I think are not needed, the replacement outriggers have no holes on the sides.
