Thread: Electric Land Rover Series IIA

I agree, that por15 stuff is so bloody hard to get it all off once it does start peeling off. (and it will) I don't think it is UV stable as I have a chassis that seemed ok (some peeling) till I stripped the body off and 1 month later all is coming off.

I used POR15 on my chassis (Stripping the original vehicle down to a rolling chassis with engine/gearbox) and have regretted it ever since. The damn stuff peels off in layers as soon as you look at it - and that's after talking endlessly to the the guy at PPC (I forget his name - the South African bloke).

It's not that hard either - I used it on the wheels, and it won't even sustain minor dings.

I would use Killrust if I did it again. Sandblast the chassis, one coat of etch primer, one coat of red oxide, then two coats of enamel.

The surface prep actually isn't that involved as I am already stripping the chassis to the bare metal due to a very bad case of the wrong paint used. I'll let you know how I go.

I've used both, and I can't tell the difference. I suspect two different companies are importing the same product and repackaging for their own distribution.

Interesting to see sideroad's comments.

By all means let us know how you go.

It's not, it requires a UV top coat. But without it, it just goes a dull black/grey colour. Preparation is the important step, as this paint is a chemical adhering paint. (And most important of all, MUST be stirred not shaken. As it won't bond to the metal and rust if you shake it, as it will bubble).

I have done the front radiator mount with POR15, and it came up very nicely.
