A soft graphite pencil could do the trick. Blend and rub with your finger.

 

Are you building one of these ??

Although not slots, I'm sure a lot of people around would like to here/see more about it.

Kind Regards

It doesn't need to be painted on. Rubber from the tyres is laid down on slot car tracks - just do lots of laps, particularly with reasonably grippy tyres.
Could be more fun than painting it on, although it might take longer.

 

Put a little black shoe polish on the rear tyres and run it around the track

 

On SR I "painted" a racing line using dark grey emulsion, a brush and old cloths.

 

Tape the lanes up and get a tin of black spray paint. Try black enamel its sticker on your finished layout ie;for grip

Heres a shot of what your trying for although this is just the drip from the sump line. Just start lightly and work your way up to a desired heaviness.

 

put a group 20 motor in your car with rubber tyre and spin it up everywhere, you,ll soon have nice sticky rubber layed on the racing line.[tounge firmly in cheek]. thats not to say it wouldn,t work. john

 

Guys, MagRacing has slow motors and really poor grip. They won't be laying any real rubber down. Paint is the only way. Plus, he wants to emphasize the racing line to encourage people to use it. If he relied on natural rubbering in, it would just be rubber all over every lane, not just the racing line.

Please check out the MagRacing link Lars provided, you might find that your answers will be different.

For example, there are no rails or slots to tape over. He can paint anywhere to his heart's content. ;-)

 

I painted it on the Dutch Trio Track in this way:
I hope this helps you.

Some paint on the track.

With a sponge you can chose big or small tyre marks.

The result.

 

Id probably use a craft paint roller for the job ,its smaller than a normal paint roller made of a soft white sponge . using a very transparent black paint .if you repeatedly roll over the same area it will lighten and spread the paint out until you get the desired effect .it would be good to test it somewhere first.

ps often areas where the road is worn out around bends tend to look smoother ,even gloss looking - texture , finish and colour combined are needed to achieve good realism , it might serve you to look at real life examples before starting this. I would imagine on a mag track you might be able to achieve amazing realism as theres no slot and traction plays less of a roll due to slower speeds.

 

Hi Everyone,

Thanks so much for your great ideas, they all sound good to me.

Hi Lars, yes, I was looking to build my first slot track, at least the first since 1967, and then I came across Magracing.

I'd seen SlotMods and was so inspired that I couldn't resist having a go. Not that mine would be up to that standard
but it sparked my enthusiasm. I also liked the idea of the cars travelling at realistic speeds so Magracing scored again.
Of course the big attraction is slotless tracks and the idea of learning a new skill of track building at very reasonable costs.

Magracing is at the stage of experimentation by Wes and his early customers which, for me, is very interesting, not
to say challenging.

For those who don't know yet, Magracing a brilliant combination of slotless 1/32nd scale cars and simple RC.
Have a look at the Magracing site for a fuller explanation.

I received my McLaren MB8A and track construction parts from Wes and I'm about half way through the building
of my new test track. The system is developing all the time and I find that aspect very exciting.

That's it for now.
I'll get to putting down my tyre tracks and then start thinking about some crash barriers.

Again, thanks to everyone who came up with suggestions.

Kindest regards to you all.
