Yeah, I was keeping it at about 45 degrees. And going downward as slowly as I could stand it, then moving over a row, making sure not to let the skin get too hot.
OK, I give up. What the heck is SS and what's all the fuss about? Is it Stainless Steel? Remember the DeLorean car? Made of stainless and my brother used to "wax" it with steel wool pads.
"Southern shine" - that's got to be a joke - the southern shine I recall would have stripped the rivets off the skin, not to mention do-da's sticker glue.
...to 45 degrees will cause more swirling. It concentrates the action of the abrasive- whether its in the pad or paste or both. Be careful.
I like to use the flattest angle possible, and tilt up to get the tougher spots to blend.
Oh, yes, very true about the angle (or something) causing swirl marks. I'm not concerned about that because according to my chosen shiny-trailer experts, swirl marks are to be expected at this stage and will polish out on the next step, Cyclo with F7. I won't get a chance to test that theory until Saturday.... wish me luck!
The reason you want to avoid swirls is to lessen the work later to remove them, and to avoid heat. Heat will warp the aluminum- and it won't shrink back to its position before you "cooked" it.
This is one reason, why I prefer to do a light wet sanding - even with 1200 or even 1600 grit, as opposed to grinding away the surface with a machine that will heat, burn, and scratch the surface. That will NEVER happen with a wet piece of sandpaper!
The second phase of polishing with the soft wool pad, and further with the foam pad, is to remove the swirls- but these aren't strong and aggressive passes- and the more damage done initially, the more work you'll create for yourself later.
When I saw FF's TW- he had used the psychlo and Nuvite, and his skin where he'd started with that was harder to correct than the untouched side. Ask him. It made me realize that a psychlo is a bad piece of equipment to try and polish with, and Nuvite is too abrasive. He'll agree, I'm sure- it was a lot more messed up than what had never been polished.
