845 continues to amaze me. I've never had issues taking it off even though my application methods probably leave much to be desired. Case in point, my dad came over last night as I was setting up to do an ONR wash. He says, can you wash my car too?
His car is filthy though. Blobs of tree sap everywhere, interior coated with dog hair and stinkeeeey (he has a golden retriever).
Anyhow, I did my car in 30 minutes then started on his. Vacuumed, apc wipedown, then 303 the front interior, sprayed down front seats and headliner with so2pure then started on the paint. After using mineral spirits to dissolve and remove all the sap, I spot rewashed, then rinsed and decided to put on a quick coat of 845.
Car had some water droplets on it but I wasn't bothered and just went over them with my mf applicator and 845. If anything, it helped the 845 go even further. Couple times I even squeezed the applicator sponge to get the excess water out then went straight back to applying it. Wipeoff was still easy peasy. Probably used less than .5 oz to do the entire car. I don't think I'd try that (waxing while the car is wet) with any other paste wax...
