Paint Removal LPW

<< < (3/3)

dieselgman:
Heated sodium hydroxide (180 degrees F) in water is best for stripping cast iron hot-tank style. Not recommended for aluminum alloy, but there are also buffered versions on the market for that application as well.
We often leave the original red primer in place after all other paint and contamination has been released and rinsed from parts.

Thanks that’s what I intend to do. I’ve got some 3M scotchbrite to scuff the red primer.
