Thread: Chassis Painting Advice - 1k rust paint v's 2k epoxy

I've always just used a good quality enamel spray can - like kill rust or similar - it sticks like **** to a blanket and is easy to touch up if needed in the future, unlike something like raptor.

On my 101, the factory sprayed bitumen over the whole chassis - 40 years on, it's a real PITA to deal with. Personally I wouldn't use any coating that creates a textured finish on the chassis.

All the best.

I've used the KBS stuff and its been quite hard wearing.
Chassis Coater Kit with BlackTop

Its a bugger to apply so I only ever applied the Rust Seal coating and not the Black Top as a final coat. I was doing the whole chassis and it was too much for one sitting - there can only be limited time before applying the next coat or you need to rub it down, but it needs a certain amount of time to cure before the next coat too - only so much you can do in a day and no way was I going to rub it all down again the next day.

1. is better though I would just recommend epoxy enamel as top coat. Epoxy will chip but is extremely tough.
2. is way cheaper but use an etch primer, as if it's properly cleaned, there's no need to convert.

Sorry to be a bother but what is "1K and 2K"?

1K generally means un-activated paints. Eg: enamel/acrylic laquer with just thinners.

2K == activated paint. Very toxic, very dangerous to health. The hardeners use are a very strong poison, but the longetivity and stability of the final coating is light years ahead of the old acrylic laquers.

The best to use would be an epoxy primer (activated). It's to toxic and too hard to work with for something like a chassis (unless you have a booth and a sandblasted chassis as a starting point).

I'd probably use a brush type rust paint as stated above. I've found even the white night epoxy enamel from bunnings is brilliant... sure finish won't be great, but who cares... it's a chassis no-one sees it!

seeya,

Thanks Shane L. I know what ur on about now. Im painting my chassis with the rust guard stuff from bunnings in satin black. It was painted by the sand blasters but they missed a few bits so ill just paint it again with a brush. Dont want to upset the neighbours with paint overspray. Thanks again for the explanation😆
