Painting underside of mudguards
« on: September 25, 2018, 10:12:12 PM »
The mudguards..or fenders on my CB400f2 look great on the outside, less so on the inside but as you can see in the pic it's not really so bad. I'm thinking of painting the undersides sometime soon....any paint recommended?

I took off the stays and carefully masked off the chrome edges and sprayed with an underseal -from memory it was called Waxoyl I believe, dried hard and protects too. Reassemble in reverse order 🤣

Hi Oddjob....so it is, I didn't see that. Well, I'm reading it with interest.

When I restored my TR4  I painted the underside  with a rust preventive  primer  then a rubberised under seal flattened then a polyethylene topcoat ,.. as the harder the paint ie two pack paint will chip. With poly paint being more flexible the stone wii bounce off without chipping..

I use silver hammerite

Gives great protection plus still looks original i.e. chrome (from a distance!)

Plus one for Waxoyl, I remember spending a lot of time treating the edges of doors and tailgates with the stuff, back when men were men and the sort of cars that I could afford were made of any old rubbish that would rot as soon as you turned your back on it (especially Ford Capri tailgates). I had a grease gun like applicator which screwed into the can, for injecting it into nooks and crannies.

It takes a bit of mixing, I still have some in a can, which will have split into spirit and wax by now.

Having seen this thread I am minded to have a go at my CL450 guards with it, as they won't be making any more of them anytime soon.

My old 911 has some notorious hidden rust traps, after advice from someone I was talking to at a car show, I painted all the hidden underpinnings with a liquid rubber product intended for flat roofs. Maybe that would work under mudguards too.

What about Zink metal spraying. Have not tried it yet but a mate has the kit to do it, not sure if it will effect the chrome from the heat. This is what his website says :
 Zinc metal spraying is used to coat ferrous (steel) metals, with an anti-corrosion coat of zinc. Surfaces are first blast cleaned to SA2.5, to provide the best possible key for the zinc layer. We use the METALLISATION FLAMESPRAY process, where the raw material, in the form of a single wire of zinc is melted in an oxy-propane flame. The molten material is atomised by  cone of compressed air and propelled towards the substrate. The molten zinc solidifies to form a dense strongly coherent coating with excellent anti-corrosion qualities, 35-40 microns.

 

There are many advantages of the Flamespray process are that the zinc coating is available for almost instant use with no drying or curing times and there is no risk of damaging the component.  The flame spray method also gives a smoother finish when compared with electronic methods of applying a zinc coating.

Sounds the biz.  Do you recommend a coating of stone chip on top of that?
Where's that 10mm socket got to?
