The 250ml version of Royal Satin is a concentrate for wipe on application to tyres with smooth sidewalls, we recommend using the 500ml spray pack for applying Royal Satin to knobby tyres where a wipe on method would be cumbersome.

To refill this spray pack, the 1L version can be emptied into this 500ml bottle and topped with water, mains water is fine, demineralised or deionised water is not necessary.
