What paint?
I have painted the chassis in Bonda Primer for protection and now intend to paint it ready for the road.
What is the best paint to paint the chassis? Enamal or normal chassis paint?
Thank you.

This afternoon I have been painting my (spitfire) chassis with synthetic paint, over bondaprimer. The synthetic is less likely to chip etc than celly
or 2k. It is often sold as chassis paint. 2 1/2 litres £20, looks like I will have plenty for a second coat and all the suspension parts. And the
inside of the car and..................
Only my preference of course, but I would def avoid hammerite and such stuff.

POR15 is spoken of very favourably and is what I used when touching up my powdercoat after welding.
I bought a kit from Frosts and it has lasted very well.
Agreed on the frailties of Hammerite.

I'd use POR15 if I was doing it again. I wouldn't use Hammerite unless it was a quick touch up job and directly to rust.

I don't think POR15 is supposed to be painted over primer, rather direct on metal. Also heard it doesn't stick well to smooth steel
needs the surface scuffing/blasting or best over cleaned up slightly pitted stuff.

Correct POR15 is an undercoat/primer as it's not UV stable, they sell hardnose paint to go over the top to get a good finish, or tie coat and
whatever top coat you like.
In my experience if you want any paint (except etch primer which does the job with acid) to stick long term on new steel you need to rough it up a
little to give it a key, I've found using a flap disc in an angle grinder gently is the quickest way. The makers of POR15 recommend
using marine clean (industrial detergent) followed by an acid etch (metal ready) to prep new steel ready for the POR15. It's very very tough
when applied according to the instructions - but also very expensive for the full system partly as you can only get it through a couple of places in
the UK.
Usually the biggest problem with powdercoat is lack of prep since a lot of places can't be bothered to blast a complex structure like a
spaceframe properly.
Synthetic over a decent primer is certainly a lot more cost effective.
ETA: If you're not spraying using a gloss mini-roller works much better than any brush for a regular square-tube spaceframe.

I used KBS Rustseal on my MGB. I'm really happy with the results.
I heard a lot of bad things about POR15

POR 15 works with a etcher- you clean back the metal, etch it and paint it. It is very good stuff, used it on the bottom of my old mini when I was
restoring it. Just don't get it on your hands- it won't wash out, only grow out!
If disfunction is a function, then I must be some kind of genius.

sorry, POR15 is only on raw metal.
I bought the small kit from Frosts that includes marine clean and the phosphating acid stuff. You do have to do it properly but when done properly it
really sticks.

Yes i did read the write up on POR15 and it made out it was to go direct onto rough metal.
I was going to get the Enamel paint, but will definately go for Chassis paint.
Where did you get it from Cliftyhanger? Do they do Red as i was looking at painting the Chassis Gloss Red and body Dark Green with Yellow stripe.

Although my Luego is powder coated, in days gone by I used Chassis Paint from my local Agricultural Merchant, who assured me it was a tough as old
boots and Pig P*ss proof as well!.
Never had any problems with it on the Landy!
POR15 from Frosts is good, provided you follow the instructions, and use the right top coats etc.
As with ANY paint, or coating, the Final Job is ONLY as good as the quality of Prep work.
Good prep will yield good results. Skimp on the prep, and it will give a poor finish. (That snippet comes from my drinking partner who is Foreman
Sprayer at Marshalls Special Bodies Divn.)
