Wetsanding plexi!!!

[RangerDanger]

Since i love the "frosted" look i wnat to add to my psu bracket i made...how should i prep it, what grit, and how many repitions????

[DaveW]

I'd like to know this too, so i'm bumping this to help out. I want some Perspex frosted, is wet and dry the answer?

You will likely get a response from Tybrenis, he is the plexi guy. But I got a decent frosted look without wetsanding, I used 120 grit followed by 220 and that was it.

[RangerDanger]

yea thx man i just tried out out 150 grit and folowed it by 220 and it cam out pretty good....except am i suppose to display it on the sanded side or the not sanded side??

[jdbnsn]

Well it depends, will it be exposed and handled much? If so, you might want to test it. Try some wear and tear stuff like trying to rub the frost off with your hand. If it doesn't look like it will hold up, probably better to put the slick side out. But overall, I think it would look better with the sanded side out.

[RangerDanger]

k thx ur barely guna see it and it will be rarely touched....

The slick side will probably look better no matter what anyway, so display the unsanded side. As with anything, the more effort you put into it the better it'll look. Depending on the look you're going for you could use various grits from very coarse to wet sanding in the final stages, whatever look you want. I'd grab some scrap plexi and experiment and see what you think looks best. Better to learn that way.

If you're illuminating it, then try gritting both sides, because then the grit will help the plexi to catch light. If you're sanding it, i assume you don't want as a window, more of a feature-i think gritting both sides with allow for a much more even glow when illuminating.

I haven't tried this out, but the theory seems sound enough.

look at the case by defyant. he does bad ass frosted look andhe explains how to do it. peace.

[The Modfather]

No, if you are illuminating it from only one side then frosting both sides will have the exact opposite effect. If however, it's a thick sheet of plastic and you intend to drill holes in the sides and mount LEDs directly into the plastic then yes, frosting both sides would look best, but I'm just guessing that's not what you plan to do, is it?
