I want to remove some small scratches in my clear coat?

These are my steps I use before sanding

1.wash
2.clay
3. Ipa

Is there anything else I'm missing. I've done a lot of g on the forum and I can't find a tread or prep work with sanding either dry/ wet

Thanks or ye fast response
 
I only do wet/dampsanding for scratch removal and buffing. IMO dry sanding is more for use in a body shop world when painting will be performed. Also when dry sanding you should be wearing a respirator due to the dry dust in the air from dry sanding.

But before you go off the deep end, have you tried machine compounding to remove the scratch or most of it before leveling your precious clear coat?
 
Yes I tried meguiars 105

And nothing happened.
 
What products would you recommend? I really don't want to do this but I Think it's the only option, however I am a newbie!
 
Can we get a picture of what your working on?
 
I live on the east coast. Dark out here

As you can see its like a t shaped scratch
 
It looks like someone wrapped sand paper around there finger and marked a t shape in the car

If the paint you're working on is the factory clear coat then the clear layer alone is going to be on average around 2 mils thin.

Feel a 3M post-it note between your fingers, this is about 3 mils thin.


This is from page 7 of my how-to book...

Keep this in mind...

Sanding removes paint
Compounding removes paint
Polishing removes paint


Only experiencing burning through your cars paint first hand can you ever appreciate the heart sinking feeling you get afterwards.

I recommend learning to live with deeper scratches if the car in question is a daily driver, see my article on RIDS here...


RIDS - The Definition of RIDS and the story behind the term...

105 by rotary buffer

If 105 and a rotary did not work, you might have compromised the clear coat. In your picture, that's what a burn through starts looking like, sort of cloudy.
 
Also, you can bring it over this week before I head out of town. I don't know if this is on the car you showed me, but I can show you how I would approach it, and teach a bit in the process.
 
I was able to take them out. I went back to the rotary with a higher spied and still with 105. Came right out.
