what should i coat my axel with?

[Ben Lessani]

Beg to differ my man, hammerite barely needs any prep work - it will paint straight on to a gloss finish and stick fast.

depends if you want a good finish or something durable. i powdercoated the rear axle on my old corsa and stonechipped the front and rear arches at the same time, the axle started going rusty and the arches looked like new after 8months when i sold it. one can of stonechip goes a long way aswell

powdercoating can be really bad news,   i just use whatever thick black paint is to hand

por 15 is worth the extra money, even if you slap it on wi a brush willy nilly the finish turns out nice.  It dries hard, almost like a plasticy coating and is very tough.  But it comes off nicely with a wire brush on a drill too, unlike some undercoatings that dont fully dry, these end up clogging the drill.

You can even get a thicker version called 'po patch' which is perfect for use as a seam sealer, now that stuff is the nadgers.

but as with all stuff really surface prep is key, por also do etch prime and rust remover products, which help get the best finish.  I just sprayed a bit o primer on the bare metal then slathered the por15 over the top willy nilly, so far its stayed on nicely

What's wrong with powder coating?

once water has got behind it your buggerd,    the rust lifts the powedercoat lifts off the metal and dosen't fall off but traps the water there whitch happily rusts away whatever was been protected by the time it falls off  whatever you had coated is competly knackerd.  once it's started rusting  the rust will travel much quicker behind the powder coat,  at least with paint it only rusts where it's been knocked or scraped   and is easy to touch up  when doing routene mantance.


and i think that as it's pritty common for subframes and axels to get beaten with 100mph + stones   or scarped on speedbumps  in the case of subframes

i just sprayed mine with stone chip

still there and it adds alittle bit of damping against the exhaust hitting it

dunno what the stuff i use is called.  i nicks it out a barrel  but engines, and bits of digga's and tractor get painted with it.    comes in various tractor colours as well

The reason that I asked, was because we powder coat all our race car suspension parts, which get hammered beyond belief!, spinning into the kitty litter at well over 100mph can completely strip the paint off the underside of the car, in one go!, yet the powder coat stay's intact, and only lightly marked, I would agree that powder coat can come off, but its normally the cheap stuff that has problems, kids bike's, climbing frames that sort of thing... proper industrial powder coating, on top of a shot blasted surface, and then the hidden areas treated with plenty of black waxoyl, will far outlast the original factory painted item

that is the kind of powder coating most places don't do.
