Bodywork question, lighly pitted windscreen frame...

Hi all,

I'm hoping someone here might be able to answer this for me.
I'm repairing the windscreen frame on my Mercedes Atego truck, due to it leaking round the top of the screen, it's a bonded screen.

There's a rusty area at the bottom that I've got to cut out and put new metal in, but at the top there's an area that is lightly pitted on the surface.

I've fully cleaned it with a wire brush on an angle grinder to remove all the rust, then I've treated it with Jenolite rust converter, and given it a coat of rust inhibiting red oxide primer that I use on steelwork.

My question is, where this pitting is, should I even it out with a skim of filler, or leave it as is and paint over it?

I've had to take the screen out due to this rusted area at the top causing it to let water in, and I don't want a repeat of that, what's the best thing to do?

Cheers Frank.

If it's where you're bonding it I'd leave it, the bonder / sealant will fill it in.

That's what I thought too, I just wondered if I was correct or not. 😀

I've had several bonded windscreens replaced and watching the process I'd agree that the adhesive should fill and seal the area between the screen and chassis. One route to check this might be to speak to a windscreen fitting company and ask for advice - they should know what they're doing.

The bonding should fill the pitting so won't need filler. The questions will be... Has the rust has been issue been cured or will it reappear? Will the paint bond to the metal well enough to hold when the 'screen is bonded (effectively) to the paint? Only time will tell.
