Special Effect Overlays This is a great way to create a unique paint job without blowing the budget, making it perfect for street cars. House Of Kolor products enable you to use an existing paint finish as the base for an exciting new colour scheme. This saves the time and expense of painting the engine bay, boot and doorjambs, etc. Clever design work and creative use of colour can add a special effect to just a few sections or transform the whole car - especially if a new body kit and wheels are being added.
