You had just applied your
AG hd and before it had chance to "cure" the heavens opened and there was nowt you could do, can`t get the van in the garage, no car port to shelter under. Damn near happened to me yesterday and I decided to buff off before the ten minute waiting period was up. I got away with it as the few rainspots that landed on it didn`t make any difference but just suppose it had got a real soaking, would you leave it to dry or go over it with more wax to remove the original wet stuff ? and how long could you leave it realistically, it might be just a shower or it could be a deluge set in for the day.
Just as an aside, the hd was an eye opener, just a little goes so far, buffs off nicely, no residue and a good shine. Did it all by hand just for the experience, I`ll use the GT220 next time just as a comparison.
