To be fair its worth doing a search as this has been covered many times

Some vote for machinery paint, Some POR 15, Some for two pack brush paint, Some just for good old Gloss paint

This sums it up well. No clear answer, each solution has its proponents and some detractors.

What did you use that did not go well?

I'm having the same issue atm. I used some E-tch gunmetal grey stuff that turned out like light matt silver and looked awful. I then went for the trusty black hammerite smooth black (I didn't know that they had changed the formula so it's now rubbish).

Been looking at por15 but from what I'm told it's not UV stable and I hate dull paint with a passion. Now looking at various tractor and plant paints, will let you know if I find something that works.

Hi,

I have used Simoniz tough black, super tough coating and chip resistant apparently. I have found it not to be very tough and definitely not chip resistant

I am currently looking at marine paint as an option, more research required though

BuzzWeld is a company that has made a great name for itself (in terms of products and knowledge/assistance) in the Land Rover world. Craig, the guy that runs it, is incredibly helpful with advice on products, prep, application etc..

I've used both Buzzweld and POR15 products in the past with good results, but have to agree that Hammerite "ain't what it used to be"....

Ive said it many many times, and have prove the following works, on an Austin 7 I helped rebuild in about 1974

A good rust preventative primer, and a good household black gloss, dulux etc

The Austin 7 is still on the road, and used and still looks as good now as it did in 1974

I have used quite a lot of POR15.
It is nice to use and brushes well.
It does go mat if exposed to sunlight for a long time but I don't think that this will be a big issue for a chassis.
There is a POR15 top coat available if you are really worried about UV

I brush painted my MK Indy chassis with red oxide primer (Johnstones IIRC) and made sure to get in all the nooks and crannies. It sticks like poo to a blanket and satisfied me in terms of primary protection. I then gave it a top coat of Halfords chassis black paint. The Halfords stuff wasn't expensive and TBH was quite runny. Again I made an effort to get it in all the nooks and crannies. Overall the chassis looked fine when painted and the majority of it was covered with bodywork when the car was finished.

On the MK Indy chassis I had the only open tube ends were the outer chassis rails that ended in front of the rear wheels. I got some square plastic plugs and PU sealed them in place to plug these tube openings.

One final step I took was to rivet some ally strip along to top edge of a chassis running across the floor in front of the seats (see photo) to prevent it getting shoe scrapes.

The primer for POR 15 gives a “rusty” surface. Is it necessary to clean up before to apply the POR 15, or I have to leave it as it is?

The POR primer I used (Metal Ready - see infosheet here http://qr.por15.com/QR-assets/downloads/POR15/MetalReadyInfo.pdf) didn't leave a rusty surface, it left a sort of white powdery reside. From memory I think I left it there, it certainly didn't seem to harm adhesion. I did have bits that didn't stick, despite very careful prep - but not linked to where there was the residue.

I should add that I ran over my MK Indy chassis prior to painting with a wire brush cup in an angle grinder and a normal wire brush to remove any taces of rust. I also protected the threads of the harness mounts. As above the red oxide primer stuck very well.
