Re: Cleaning of metal prior to painting

I need more info to help you.

1. Are they hand wiping ( bucket and rag)?

2. Immersion cleaning- dip tanks?

3. Conveyerized spray washer?

4. Pressure cleaning with hand wand- steam cleaner?

5. Is a pretreatment used?

6. Any chance the galvanize passivated? If so paint will not stick well at all.
