Nautical- Close, but no cigar (at least he's not getting one from me

). If it works for him, great. Really. Not knocking him at all. But if *I* washed like that I'd mar things up. I know because I've done it that way in the earlier stages of developing my current method.
(For the umpteenth time; I only do what I do because it's the only way I can avoid marring. I hate that it's so labor-intensive and I wish I didn't have to resort to such off-the-deep end [nonsense]. I'm sure not trying to impress anybody with how fancy I make carwashing, or to make it sound like anybody else oughta do things my way. So when I get all critical about somebody else's method I'm just pointing out why it wouldn't work for *me*.)
Two Points:
1)He's not allowing the foamgun to flush away the dirt; he lets it get trapped in the mitt and seems to believe it'll be held up in the nap. I don't rely on that, I try to keep the dirt from getting stuck to the mitt in the first place. So I hold the (wash solution-filled) mitt shut by the cuff and gently whisk it across the panel while spraying the foamgun. I don't press the mitt against the paint the way he does.
2)He moves the mitt in long motions under continuous pressure, i.e., all along the length of that car's roof; I move my wash media in short, interrupted, "jiggling" motions so the foamgun's output is more likely to flush away the dirt (during the "pauses" in the mitt's movement) and, perhaps more importantly, so that if I *do* somehow get marring, it's not some looong scratch but rather some little short one that'll be less obvious.
If I could change *one* thing about how people wash, I'd probably be to quit using long/sweeping motions that can result in long, obvious scratches. OK...I'd change two things- And rinse/redunk the mitt/etc. very frequently instead of waiting until it's obviously necessary. Just those changes might make all the difference for some folks. Assuming anybody needs to make any changes....
