Removing factory scale from tubing?

[mhorowit]

Do you remove the factory scale from 4130 received from a supplier, or just scuff it up prior to priming? - Mike

Mike,
If you're talking about the "shiny finish" on a new piece of tubing, I try to use a bit of Scotchbrite to scuff it off before welding around the area that is to be welded, then a light scuff all over and followed by DX330 (follow the directions closely) just before priming.
