Repainting underparts - best paint??

Post by swampy42 »

Presently restoring a traveller and wish to paint suspension parts, pedals, prop shaft etc. Just wondering what the best paint to deal with these components would be. Would I be laughed out of town for using smooth Hammerite?
Thanks in advance

The thick cast stuff, such as suspension parts, drums, rear axle etc I cleaned and scrubbed in turps then used black smoothrite. they came up really well and fairly cheap only using two small tins.

The underside of the car itself I used POR-15... more expensive and it took longer due to the prep required, but gives a very hard durable finish.

Smooth hammerite is ok if you're selective, many don't like it, and perhaps not for the prop, as being quite a 'heavy' paint may spoil the balance if not put on evenly

I've painted a couple of parts in smooth Hammerite and although they look clean and new, the're a bit too glossy in my opinion and just wondered if there was a satin alternative - something closer to how they would have looked when they left the factory?

Halfords do tins of high temperature paint in satin, gloss and matt black. I have found it covers well, dries fairly quickly and you can clean brushes with white spirit. Similar prices to Hammerite.

It sounds like a combination of the POR-15 and satin Hammerite might well be the ticket. Many thanks to all

POR-15 is good, but expensive and can flake if not prepped/applied correctly.

Hammerite is good and in my opinion gloss is best for the parts you wish to paint as any future rust/chips will show up a lot more clearly than had you painted them matt.

Hammerite and smoothrite does not work as advertised. The rust comes back in a few years.

I've never used POR15 but have recently started using Brantho Korrux 3 in 1. Mainly because the UK importer is next door to my workshop!

It is a really nice to use paint and promises 15 year anti rust protection even in marine environments even on already rusted surfaces. TUV approved as well.

By the way, Finnegans never could get Hammerite into the German market as the Germans tested it and found it does not work as advertised.
Cheers John - all comments IMHO

My workshop neighbours; IPCS lts sell 750 ml tins for £21, which is actually cheaper than buying Hammerite by the 250ml tin, although a 750ml smoothrite tin is cheaper at £18, but I'd rather pay £3 extra for a product that actually works!

Although postage might be applicable to this if you are not in the same area. BTW this is the paint you see protecting high value structrures for years such as huge oil storage tanks, metal road bridges and even Trawlers!

Imported in the United Kingdom by:
I NDEPENDENT
P ROTECTIVE

Regarding POR-15. I have used this, was impressed/concerned about its sticking power on human flesh! Doesn't shift with thinners once it starts hardening (very quickly on skin :( )
Found it holds very well on rusted/rough surfaces, but peels off new metal (may be not if you use the associated and similarly expensive primer). Also brushes rendered pretty much useless ( maybe not so if you use the similarly expensive brush cleaner, etc etc!). Certainly a very high VOC product, gives blinding headaches even used in fresh air underneath the car!

Hammerite- unless you can buy some of the pre-VOC clampdown (2010?) version forget it. The modern stuff is just like any black solvent based paint. The "proper" stuff used to string from the brush as you applied it, could not be re-brushed to tidy up runs etc, and again, stunk to high heaven! Just bought some rusty old-stock tins, and there is no comparison with the latterday product!

Best thing I have used so far on sheet metal underside has been Tetrosyl, slow setting, and stays pliable when set.

I'm pretty sure Hammerite tins used to indicate that it shouldn't be over painted with second coat for 6 weeks if not done within 24 hours. It doesn't say that anymore!

Never had any problems with hammerite/smoothrite. Provided the surfaces to be painted were free of grease, flakey material, dust and were keyed correctly.

I've earnt a few tins by being a helpful neighbour! ;-)

I'm also trying their "Nitrofest" primer at the moment which seems very thick but sprays well with very little overspray. I have to test that one a bit more to see how it goes. In fact I'm tempted to do a "Practical classics" style product test. Compare various products painted onto rusty and clean steel samples and screw them to the wall outside the workshop and see how they weather the elements over the winter.

That would be interesting - go for it! Include a rusty sheet sprayed only with waxoyl - since some believe it has magical rust killing properties.
