Anyone used 3M Underbody Schutz coating?

Anyone used this on wheel arches, floorpan etc? I was planning on using Upol Gravitex but wondered if this was better? You can't paint over it like Gravitex, but I think it is more rubbery. My car has been rust proofed in the boot and under the carpets with a thick rubbery paint and I wanted something to repair the bits that need scraping off and redoing. The 3M sounds ok for that, but if it's decent stuff I'll do the wheel arches with it too.

I've never used 3M car products but you expect them to be good because it's such a big brand.

I used it on my 2cv and liked it nice tough finish when dried

Its very good stuff but as you mentioned the bugbear is you can't overpaint it.

Another good product is Rubberloid but havn't seen it in a while.

dont like it excpet for banger type cars ...all the stones /grit stick to it and makes a mess and horrible if you need to work on the car

if its a decent car id use the overpaintable one and top it with gloss , washes clean then and easy to spot any new scabs
