So you're lucky enough to have the space for a permanent slot car track setup but it's missing something, somehow it doesn't look right. Well that something is most likely realistic looking scenery for your track layout. This 'how-to' is an introduction to the products and techniques you can use to create your own version of Bathurst, Le Mans or Monaco right in your own home.
As an alternative you can buy plaster of paris in powder form, (Uni-Pro produce it, available in most hardwares) and using chux cloths you can achieve the same outcome. This method is MUCH cheaper although it will be a messier and you will have to work quickly or do small batches of plaster.
You are only limited by your imagination when it comes to adding detail to your new layout and the more you add, the better and more realistic your track will look. Checkout some of the follow-up scenery tips and tricks pages I've linked to at the bottom of this article; signage, helicopters, team transporters, pit lane buildings and even construction sites!
