Chassis painting anyone tried Hamerite metalmaster?

Hi,

Is it a gimmick or does it work? could make touching up the chassis rails easy.

Well fella it works on everything else and should work for us.

This has just been reviewed on the gadget show on channel 5 along with some other DIY gadgets, not a comprehensive test but did get the vote for the best of the lot, showed a quick demo of it & it did look impressive, managing to paint all the way round some iron railings when just pointed at the front!
Has anyone tried one on a chassis yet?
Cheers Andy

I assume you would have to earth the chassis to the ground for it to work?

Has anyone used Hammerite Metalmaster http://www.hammerite.com/uk on their chassis yet or is anyone contemplating using it? Thoughts vaguely turning to autumn/winter jobs and this might be a good way to paint the bits of outrigger and chassis that I normally can only poke a brush at.

I'm sure it'll do some good but don't be fooled by the clever advertising. This process needs space to work. The statically charged aerosols of paint need space to flow through like lines of magnetic force. With the under body being so close to the outriggers I would doubt any paint could find its way to the tops of the tubes. For other parts of the chassis this process is likely to be worth a try. Also, if you've protected your chassis with waxoyl then you'll have to remove every trace of wax before giving this a try.

Simply put, the system ejects a very fine charged mist of paint. That charged paint is then drawn to an opposite charge on the item to be painted. If the fine mist is obstructed by the under body then it won't be available to be drawn onto the tops of the tubes.

Good point and taken. After a good cleaning, I Hammerited and then waxoiled my chassis as thoroughly as I could nearly two years ago. Fortunately it's in pretty good shape so I'm interested in keeping it that way. Very little wet driving since. Still have that niggling feeling about the tops of the outriggers and the awkward to get at bits of chassis - with the electrostatic application I agree that it won't work where there is wax in place but if there is wax, it has less need of a painting. I am also under the impression that Hammerite contains Zinc and that this acts as a sacrificial anode - ie the zinc, being a stronger anode than iron will oxidise in preference to the iron in the chassis. If I did use the Hammerite system, I'd re-wax it for good measure after painting.

I suppose that the questions that I'm asking are: how easy? Did the job appear to work? Was it quick to apply and was there much overspray? If you are a Hammerite fan as opposed to a POR 15 fan, would you consider using it or would you use a brush?

This looks interesting but from downloading the instruction manual I dont think it will work very well for the outriggers, see excerpt from instruction manual regarding Plastic!


“4.1 Garden furniture and non-fixed
items should be positioned on a
groundsheet (not plastic or rubber)
prior to painting. Plastic and rubber
can interfere with the flow of
charged paint particles.

4.2 To avoid overspray it is
recommended to mask areas
in cardboard rather than plastic.”
