Any recommendations on paint for suspension parts

Post by roymck » Sun Nov 10, 2019 9:48 am

Can anybody recommend a Black or Satin Black oil based paint that can be used on new suspension components prefer without primering . Also something that can be brush painted and leaves very few brush strokes and will resist rust .
Am I asking too much for a paint ?

POR15 is the favourite but I don't know if it comes in satin

Controversial choice, but I use hammerite smooth and clean the road film off it annually before dabbing in any chips. Can be painted without primer and even over rust (though I don’t do that).

POR15 etc. are supposed to be way better, but are very expensive. My approach works for me :wink:

My first thought was Smooth Hammerite but I don’t think it’s as good as it was many years ago , also don’t think it’s petrol resistant . Used to use Valspar enamel but my last tin finished many years ago , paints ain’t what they used to be !

I’ve had fair results from Hammerite garage door paint.

Now I tend to spray in 2k if I can.

If you must use paint, my choice is always garage floor paint. BZP is much better though :)

Correless is flexible, not like hammerite which can chip when hard. It's also a rust protector/converter. I think the only reason that hammerite is not impervious to petrol is that it takes at least two weeks to properly cure. Certainly, the parts I've painted and left are fine with petrol, whereas petrol is great for cleaning hammerite spills etc.!

Has anyone used POR15 and then wanted to remove it after a few years? I understood it is quite difficult to do, which is why I've steered clear ( :) ) of using it.

It being difficult to remove is surely the point

I used to use hammerite for subframes/chassis and suspension parts but it does have a tendency to chip if impacted.
Tried some of the zg90 cold zinc galvanising paint but I was left very disappointed with it. While the ZG90 seems to be very resistant to chipping but its corrosion protection, on clean and not so clean steel, doesn't seem to live up to its claims.
I even tried over coating it with another paint which did help but it doesn't seem as good as the hammerite at corrosion protection.

I really must get some POR15 and give that a try.

The answer to the question is epoxy primer, as always. Far superior to POR-15 and etch / zinc paints and very much cheaper. Totally inert and waterproof once cured and can be overcoated with anything you like. For brushing, go for Jotun or the same thing in much more expensive tins, Rustbuster. For spraying LECHLER 29107 can't be beaten. Prep is to clean and key with 120 grit. Curing is about 12 hours but can be overcoated earlier. Adhesion beats anything you may have tried before and if you want to remove it once cured, you will need a dangly grinder.

POR 15 is very easily removed with Cellulose thinners and brake fluid, hammershite also don`t like brake fluid.
Most of my refurbished parts go to a local Stove Enamelling company, let them do the hard work, and I just remove the over covering IF a part needs a machined surface.

Top and bottom wishbone arms work out at only about £5 each if you bolt them all together.

I still have some in stock if you wanted to try them Roy?.

Which Jotun is the best to use?
Just been on the website and there is a lot of options.

Bit late but KBS coatings is a more developed version of POR15....see KBS website......attachment is by an independent USA user.
KBS coatings RUST SEAL vs POR 15.pdf
(30.5 KiB) Downloaded 20 times
Hammerite changed formula a few years ago......I used it in early days and found it a waste of effort in-spite of my meticulous prep.....lost most of it off front suspension very quickly.

I have demonstrated at our noggin and other club noggins hitting KBS hard with a hammer and flexing it on a metal sample showing no marking/cracking occurs. Big snag is the preparation and application process. Brushed on it cures to a smooth finish with no brush marks.....gloss or satin.

Big snag...there seems to be no retailer in the UK since the lady in Devon that used to import and sell gave up.
I have been trying to persuade Holden and others to give up selling POR15 and import KBS Coatings products instead.......perhaps if more people hassled them they would ???? :D ....have sent them the attachment.

Anyone out there prepared to do us the favour of importing and marketing the KBS Coating products? (AJL???)
