In reply to rachelbairdhall: Base waxing and edge tuning can be learned from youtube, from personal experience base fills of scratches are always better done by someone in a shop with a properptex gun rather than one of the candles which tend to be softer and rip out.
I use a Toko edge tuner and a Boots mini travel iron to wax and it does a good job between full services.
