Do you really need the foam? Can the fact that the foam is missing be seen? A cheap option to replace it is a can of expanding foam - just a fiver at Screwfix.

This is a new bomper for my own car - a Ford Mondeo Ghia X Mark 1 of 1995 vintage. I just need to "glue" the sections of the expanded polyurethane foam together, but unsure of a suitable product, preferably in spray can.

I want to be able to pull the bumper apart slightly, just to be able to spray and then compress the damaged areas, while the bumper is on the car, as the break in the foam is only on the one side. I want to avoid removing the bumper for repairs, as the access to the fixing bolts is very difficult. Would a can of "expanding foam" work, presumably this is known as "polyutherane expanding foam", or what is a correct description?.

Thanks for the help

Oh! It sticks all right! Got it on my shirt and jeans last time I used it. Won't come off.

When it first came onto the market many years ago, you had to buy a pack of two chemicals which you mixed together. It was sold by those specialist glass fiber shops like Strand Glass which were around in those days, and it was quite expensive. Now all builders' merchants sell it in shake-and-spray cans and it's quite cheap. Wilko sell Pollycell 'Expanding foam Polyfilla' for just under seven quid. But if you only use a bit of it, it solidifies in the nozzle and won't ever work again. Yes, squirt a bit in - but watch out as to how much it expands! You'll probably need just a little sqirt (like me). Wear gloves. If you get a bit on your hands, it's a job to get it off.

Acetone (nail varnish remover) dissolves this off hands and will unclog the nozzle too.
