Personally never had a problem with applying BSD, it's a spray wax reallyIf you ever have a bottle of Sonar BSD and Chemical Guys hybrid V07 detailer try mixing them 50:50 in a empty spray bottle. It works really really good, makes the BSD easier to apply and less smeary/thick.
Little tip I picked up on from detailing world, reminds me I need to buy more of the stuff.
