Painting metal

[Steve Bullman]

im patching up my truck at the moment....not the cab, just the metal work on the tipping unit. last time i used hammerite, it didnt last as long as i hoped, could be either because of the abuse a tree truck takes....or i didnt apply enough coats......or the stuffs crap.

what are your opinions on hammerite over red oxide followed by metal spray instead? obviously hammerites easier and quicker but is it worth spending the extra time with the oxide?

[Mr Ed]

Hammerite is for hobbyists. Waste of time for proffesional use. The key is your undercoat. Use a high zinc content industrial undercoat, use about 30% thinners, and give it 3 coats. it'll dry in about 1/2 hour. get this right, and you can even use dulux as a top coat.

Hammerite dries brittle, so will always wear and peel. use a 4" foam roller to apply, and you'll get a decent finish

high zinc content...is that different to red oxide?

so to confirm, what paint would you actually use on top

Marine 2 pak..

The best thats easy to apply would be Jotun Marine paint. I have a supplier on my doorstep. But if you undercoat properly, even dulux gloss will be fine. I painted a chip truck with dulux garden gate green, and it looked great.

Stay away from 2pack unless you know exactly what your doing.

 

What colour do you want?

[Steve Bullman]

silver

 

i just painted the back posts and the 2 side posts with hammerite as they were looking a bit shabby, but im thinking of spraying the whole back frame silver

[Steve Bullman]

i just bought some anti rust primer made by International go try. is it worth using up the hammerite i already have for the top coat or will it be crap even for that? ive already done the posts and the colour is what im after see

[Mr Ed]

For those posts the hammerite will be fine. I would'nt recommend painting your alloy boards though. Use some neat Road traffic film remover to bring them up good as new.

im not painting the ali.....just the metal parts of the buck and the bulkhead
