Not at all blotchy or streaky. Seats were super clean to begin with. I started on the passenger seat first, I will try to do a 50/50 on the driver seat if time allows. I put the UFO applicator in sandwich bag and will keep that applicator dedicated for Leather Conditioner only. I don't see then need to clean it as long as it doesn't dry out. Once the bottle of Cleaner hits the 50% mark I will add distilled water.
Very pleased. My guess is I won't be able to go 3 or 4 months before I reapply the Conditioner. I have a pretty solid OCD thing going on with weekly maintenance. I am either washing, cleaning door jambs, Floor Mats, Quick Vac or cleaning the glass or doing an interior wipe down. Not all at the same time ... one of these things takes place on a weekly basis.
