Chassis Paint

[S3FHC]

Hello all,

I am about to start reassembling my car and I will start with painting the chassis, it has already had a protective undercoat applied to it but I would like to finish it with an original paint finish.
Any ideas what colour it should be and any recommendations of a good brand? I?m in the UK.
(I will be painting the wishbones too)

Thanks,

Mark

I painted my chassis in satin black Hammerite and gloss black for the wishbones. Having used Hammerite for donkeys years I still think it produces a great finish that for a brush on product is as tough as old boots.It doesn't even require an undercoat. I also use Trustan as a rust killing product and IMO it certainly does kill the rust for good.

I've found that Hammerite doesn't like Petrol very much

Por-15 it's good stuff.

I recently sprayed a chassis in their red Oxide, i think it was a little on the brown side next to the sample but acceptable. I used their Semi gloss chassis black straight over shot blasted metal for the wishbones etc.

Personally i epoxy powder coated my chassis a BS grey as close to the engine colour as possible (i have it written down some where). I couldn't bring myself to paint it red oxide.

Yes I just used grey Por-15 followed by their Red Oxide top coat myself:

Took 10 days to get the stuff off my hands!

My original 1972 Chassis appears to be Red Oxide with a bitumen like coating:

I think the colo(u)r match is close enough!

All comes down to personal preference. I personally can't see the attraction of red oxide and I don't think it is so resilient to the elements as products such as Hammerite. The biggest attacker is brake fluid!

This is Por-15 which is Red Oxide in colo(u)r, not Red Oxide paint... big difference.

Opinions are like Belly Buttons, everyone has one!

As above, Por-15 is the modern day Hammerite and it's much more solvent and corrosion resistant.


I agree about the colour though, i didn't like the colour but then if you want it original your options are limited.

Another vote here for POR15. I happen to like grey chassis and the POR15 grey is perfect for my taste. They do recommend sand blasting before painting POR15. It is easy to touch up and seems to be remarkably resistant to both brake fluid and solvents and to chips and scratches.

At the moment I favour Jotamastic 87 which comes in various colours and formulations - I am using the 87AL in Winter grade. It is essentially a 2 part (4:1 mix ratio) epoxy paint, I have attached the data sheet. Significantly cheaper than the POR products - which I have also used and after much trawling Jotun has been used successfully as a chassis paint. Have also used Hammerite and it is not as bad as some would have but does chip too easily.

I clean up with Phosphoric Acid (readily available) dry off and paint soon after. I have used both brush and spray with Jotun 17 thinners - about 10 -15%, 2.0 nozzle in an HVLP gun, 40psi at the gun. Sprays really well. Have only done the wishbones thus far, 2 coats. Finished Jotun readily accepts topcoats (for colour) should you wish.

Jotun epoxy is good stuff, i use it a fair bit combined with Dupont Epoxy. I'm a bit of a Epoxy fan, just make sure you have the appropriate thinners to clean out your gun because if it sets it's going no where

I just think por-15 is a bit more user friendly.

Thank you all for the replies!

Isn't Por-15 an epoxy base coating ? I have not used it in a while since it's not as easy to source in Europe than in the US, but that is what I remember of this product line...

From memory (i could be wrong) POR-15 is a moisture curing Urethane.

I believe the same company dabbles in Epoxys too but i'm fairly sure they made their name in Urethane products.

Urethane is great for chassis etc as it's hard as hell when cured and has very good chemical resistance. It also sprays really nicely when thinned with the Urethane thinners, a bit like Epoxy though make sure you have plenty of appropriate thinners handy because it will wreck your gun if not cleaned out thoroughly before it cures.
