Surface rust???

It is possible that the rust is from the screws that retain the covers, they do not use SS screws. can you post a pic?

The coromal has alluminium sheeting, no metal. Allum.. will not produce rust stains.

it may be steel fragments from the grinding of the old bumper that would have been made from steel,remove with water blast or soap and water wash.they will continue to rust if not removed and may stain the vans surface.

I would be more worried about how adding all this extra weight to the rear of your van will alter its load dynamics and handling than a bit of surface rust.

When grinding it pays to either vacuum all the dust or blow it off with an air hose

All vans have a Legal ATM and an allowable payload which is pretty hard to stick to without adding fuel and bikes to the rear.

This will lighten your ballweight and a tail heavy van is certainly not a safe van.

Also carrying fuel , especially petrol on the rear of a van is rather dangerous.

Lots do it I know but on the A frame is safer.

Coromal also recommend that extra weight not be added to bumper bars due to the extra weight adding to chassis flex..

With my 754 I could not do that anyway as it would exceed the overhang legally allowed. I had to bolt my spare carrier on to be able to say it was temporary.

Adding about 80kg to the bumper has to come out of your payload and when you hit a big bump will be multipied several times putting more strain on the chassis.

A lot more to it than just doing it and not thinking about the consequences.

Once you have thoroughly washed and dried it, give it a good coat of polish like carnuba wax (would be good to do the whole van and car too) to prevent the rust from staining. Carnuba cleaner wax will get rid of oxidisation (paint fade) and stains if it has got too bad.

A dose of penetrol will seal it up and prevent rust unless it's chipped off like any other paint.

Guess we lost the other thread..............

It was entertaining while it lasted'
