Wet sanding, and recoating?? What steps?

[Guest]

Depending on how bad the garbage is, you could wet sand with say 2000 grit and buff it out. An occa dust turd ( unless it goes to and shows the substrate ) is easier to just sand off and buff out vs sanding and recoating the whole thing...Otherwise, yea that's pretty much what I do. I use denatured alcohol though instead of pre and make sure to get rid of any lint from wiping it down.

What steps do you use to wet sand, or other methods to remove garbage from item. Is it common to wet sand out, wipe with prep, and recoat?

I have done these steps below and it came out MIRROR finish. (Black was the color)

1. Let the substrate cool.

2. Grab 400 grit wet/dry paper and put water in a spray bottle or water bottle.

3. Sand EASY with the substrate and sand paper soaked with water, be sure to keep everything wet at all times.

4. Yes, it might not feel as you are doing anything. (Give it some time)

5. Dry the substrate and look for imperfections.

6. If you still have imperfections keep going with less water.

7. Imperfections are gone. I try to take all of the shine off the part (gloss). Look at the substrate with a light for this.

8. Substrate has no shine and imperfections left. Find 1200 wet/dry sand paper and go at it again with the water.

9. Keep going until the substrate looks like you coated it with a flat powder. NO imperfections bumps or humps.

10. Clean substrate with water and dry.

11. Clean substrate with denatured alcohol and dry again.

12. Re-coat substrate. (If you are using a manual gun, I would set it at 20-30KV and 70-80AMP OR 80-90KV and 15-20AMP) Depending on how the powder acts to the substrate. If you use the higher KV setting stand back 18-20 inches.


I hope this helps, it worked for me.
