Thank you so much for the concern sir. I will stop using alcohol from now on. Since you said that it would be dangerous to pry the grips off the hilt, i will go with your suggestion to mask and paint with chrome marker sir. Thank you so much. I just wish that part is real metal (aluminum or real chromed metal) so there would be no fading issues. I will update this thread once i'm done with my chosen process (masking and repainting). Thank you to all of you sirs. You were all such great help for me. I sincerely thank you all.The grips do use pins/tabs to 'snap' into holes in the saber tube body but there is also glue so removing the grips could break the grips off when trying to remove. Because it's just on that plastic part you can easily mask off the grips and the chrome tube parts and just paint the plastic part with little trouble.
The Molotow chrome paint pens are super easy to use and give lots of control, it's like coloring in a coloring book just stay inside the lines. I've used SpazStix chrome many times and it's awesome but you do have to spray a gloss black first then spray the chrome over top. Because of the grips you hand will probably not come in contact with the repainted surfaces so wear should not be an issue.
My question is why are you using Alcohol to clean your sabers? Better to use a water-based cleaner with an included degreaser instead. Using alcohol over time can dry up plastic and cause it to crack, and you've already seen how it can effect plated/painted parts. Alcohol is not a preferred cleaner if you're wanting to keep your sabers in prime condition long-term.
