Orange Peel

Hey guys, I was wondering what you guys use to knock it down with to make if flat as glass?



600 on a block, and reduction sand all the way up to 2k?

Or would 1200 on block fully remove it to be flat, w/o sacrificing all the clear starting from 600?

If this is confusing to understand, let me know. Sorry.



Thanks!
 
Well at school we start w/600, because it would most likely take the peel out the fastest. But I want to do my doors, which have been repainted and I don't want to use 600 sacrificing the UV protection. So I was curious as to what grit I could use to successfully knock it down and make it completely flat, and buff less.
 
So starting from 1000 will succesfully knock it down and make it perfectly flat John?



Just double checking, doing my car. (Black btw) :D
 
Shoot, you can get it perfectly flat with 3000 grit...just that the sun may go nova before you get done. Listen to these guys, they've done it a lot more times than you have ;)
 
I'm not doubting anyone, I've wetsanded quite a few cars before after painting them.

However, I've been taught to remove peel, (from a door for instance) to start w/600 on a block to cut if fastest, and to make it FLAT, then reduction sand up to 1500. Which is the highest grit we have in school. I simply was just curious as to if a higher grit could give me the flatness :)
 
Yeah, but the term FLAT, in the context that you are using it, doesn't have to do with the flatness of the surface, it has to do with the peel being gone. The actual flatness of the surface is going to do with your technique and your block setup, not the grit of the paper. The reason they tell you to go FLAT with the 600 is to save time in a production environment, when you're knocking down peel from the paintbooth. What you're trying to do here is a finesse process.
 
If you ever go through the clear by using sandpaper that's too aggressive............ you're buying a paint job.



It pays to be a little conservative and take your time.:bigups
 
Removing orange peel, and making the surface flat, really, are two different things. You can remove the orange peel and still have a horrible looking surface. If, like you say, you want the surface like glass, the sanding part is going to require that you sand in such a way that "blocks" the paint. Blocking and sanding is a technique used by painters to get a surface perfect before paint. The same blocking and sanding technique is carried out through the final color sand and buff to knock down orange peel.
