Deep Hairline Scratches

[tonysandiego]

Anyone know of a mfg. or retailer that has a good selection of shop stools with logos on the vinyl seats?? I've seen the ones from California Car Cover but they don't offer the brands that I'm looking for. Would like to find one with a BMW logo or Porsche logo on the seat.

Doesn’t have a Porsche or Bimmer logo on the seat but it looks like it might be as fast as one!!! Sorry my net search didn’t find what you asked for but I tried.

This may be a dumb questions but I am wondering how you know when a hairline scratch is to deep to wet sand or polish out. Let us say that you did some spot compounding and you leveled some of the scratch. How many times would you hit it again to try and remove it? Or how would you know when to try to wet sanded out a scratch. If anyone has some good before and after pics that would be great. I am sure a paint meter comes into play most of the time in this situation.

Thanks

not dumb at all and GREAT question. I've battled the same thing and sometimes resort to slightly wetsanding to round out the edges a little more then buff. It's that ONE scratch somewhere that won't go away. I try to "minimize" it.

I also have a fairly inexpensive magnifying glass I use sometimes to take a closer look. Most of the time I can see that it's too deep to correct. The problem I have is exactly what you describe i.e a very thin but deep scratch. It looks like it should buff right out because it's so thin but because it's deeper than all the others it won't be fully removed.

thanks Puckman. I am sure that experience also plays a part as well.

Deep Scratches

A surface scratch that will `catch' your fingernail is approximately 0.04 Mil (1.0 ?) deep will usually require wet sanding and the clear coat refinishing Removing a scratch requires removing the layer of paint that contains the defect; you need to level the paint to the lowest point of the scratch. Removing more that 0.5 mil (12?) of clear coat will cause premature paint film failure as UV protection percolates to the top of the clear coat.

As you go over a deep scratch, the abrasives round off the edges of the high spots of the scratch. The result is a shallower scratch (when no full correction can be made) rounded edges don?t reflect light the same way a sharp edge will and is therefore less noticeable.
