How to sand out a run, so you don't see it after buffing.

Next day, I take a 320 DA disc, fold it and with just my index fender, sand the high spot of run, sand with the run so you are not sanding the good clear next to the run.
Within one minute the run should be level with the good clear, then I will take a paint stick with 1500 wet and do a quick blocking of the clear.

There are a 100 ways to sand out a run but this is one idea that may work for you, hopefully other people will have some better ideas.
 
I do a similair technique.
Being as I an such a clumsy dorf I take a psa backed disc and cut it into circles about 3/4" - 1" in diameter. I stick them to my pointer finger tip and sand.
To cut the circles I use a 3/4" steel pipe that I have ground one end to a sharp edge.
I place it in the vise, lay the paper over it grit side up and whack it with a rubber mallet.
Only takes a couple minutes to make a 6" disc into many fingertip discs.

Its also a great stress relief when the wife has irritated me, I get to take a hammer and beat on sumthin other than ... .... LOL
 
i use 320 too. only way to get it flat. i jump to 8, then 1500.
 
Have you guys tried Shine's trick of covering the area with wide tape, then using 320 (wet?) to block the run down through the tape, the remaining tape protects the surrounding area from deep scratches.

I haven't tried it yet, but will on the next nice hanger I get.
 
I have tried Shines way and it does work good.

I have also tried wiping glaze over the runs, like dolphin glaze and that does work, only tried it once but seemed very time consuming to me.
 
The reason runs telegragh through even after sanding flat is because the
clear is softer in the run (due to its thickness) than the surrounding clear.
It will always sand and buff differently.
The best way is to level it close to finish and then let it cure another day or two
before sanding it out completely. By reducing its thickness it can catch up to
the surrounding hardness. The longer you wait the better.
 
i would agree, but u need to get the bulk of the run out before it gets too hard.
