I’m looking for suggestions on which paint to use for rail tubing I don’t really want powder coat as its going to be used off road and may need mods in the future and I don’t want to spray as it uses to much paint to go all round the tube so looking for a good hard wearing paint that flows well doesn’t show brush marks and can be touched up easily had thought about hammerite but this does tend to chip easily or maybe one of the industrial equivalents. If you have any experience good or bad of any pain then I'd be interested to hear

Truck chassis primer, or truthfully just red oxide, hand paint it with 2k for your finish colour. Don't let anyone kid you you can't hand paint with it, because you really can. Do agree with not powder coating, as you say alterations will be a problem as matching in is pretty much impossible. The other thing to take into account is, they're all getting old now, rust will be deep in some of them and powder coating won't like that, even after sandblasting and zink priming. Hammerite really is just plain nasty.

Thanks bob never know you could brush 2k. Have you ever done this, dose it flow ok do you need a mask and dose it need baking or just add more catalyst and work quick ????

just found these pics of your fug if this is done with brush Then I’m very impressed

Just mix it as you's spray it, little less thinner though, just get it so it's the consistancy of typical gloss paint. It doesn't need baking, you could use a mask, depends on how much you're using and how confined the space is you're doing it. As it's brushed there isn't the mist of spraying, it's really quite easy. I've actually used it in the house, it's better than Dulux :D And yes, my Fug is done with chassis paint, dry flatted and then 2k, all done with a brush. It makes repairing damage and painting moved or altered tubing a quick job that costs pennies.

POR 15 and KBS Rustseal are moisture curing polyurethane finishes which are very tough but they do need over coating as the finish, though not the protection, is affected by UV light.

I am also looking at Epoxy Mastic 121 for mine.

Have to agree, they are good products, not used them personally, but know of them being used on tugboats and beetle floor pans. To be fair, if I were painting something like railings on the seafront or the bottom of a rusty fishing boat, that's exactly what I'd use. For painting good condition steel tubes, commercial chassis primer and 2k is good enough for me. My fug looks the same as the day I painted it, should it go flat it'll polish up the same as a secondhand car in a showroom. Would however be interested in quality of finish and useability with a brush on a Fug.
