    Strangely this is the only reference to POR15 that Google can find on Smartz

    Assuming I can fix the engine that's just blown up (still not sure what the failure is), I am going to have to use a fair amount of POR15 on the underside of my car, because it is a disgrace. Was there any corrosion protection on these cars at all?

    I also need a new Cabrio Undertray if anyone happens to know of one for sale. I have a standard ForTwo undertray that is available to collect in return for a small donation to Help For Heroes.

    kurust works well pull your rear arch liners out & look at the bit towards the front of the car that's where smartie needed it!

    I used Upol Gravi Gard on mine, goes on quite thickly and seems flexible enough not to chip. Took the arch liners off, to be fair only a bit of surface rust, not bad for a 1998 car.

    I saved my 2002 Cabrio using two pack epoxy from Rust Buster followed by Body Schutz bitumen where suitable.
    Agree the original paint protection is bad. Mine was really poor under plastic door sills.

    Por15 is poor. Rustbuster Epoxy-Mastic 121 is the clear winner: http://www.auson.se/sites/default/fi...nthly_uk_0.pdf

    Brilliant test, and very informative, thanks.

    However it's not representative of how I've used POR15 on my Cerbera chassis, nor how it will be used on the Smart, as the test was on new bare metal.

    I have not taken the surface back to bare metal, not just because I'm too lazy, but also because it's not accessible (not without a body lift anyway). Instead it is applied on rusty metal that has been wire brushed to remove loose debris, and then I spray with brake/carb cleaner to remove dust. I've also reapplied at three year intervals so far, although I'm not sure whether I'll do so again in another three years.

    Using it on the Smart will be a pain, as working upside down is going to be really horrible. I may try thinning and spraying, rather than using disposable brushes, but I suspect that it will simply drip too much.

    These are not proper before and after photos, because you can't really see the chassis with suspension back on, but you get the idea of the level of preparation from the first picture, where you can see the original grey POR15. The second shows the new satin black POR15.
