[QUOTE="Lindsay1718"]I sanded it 1st w/ wet dry sandpaper 600, 1000,1500,2000 then I used novus 3, then novus 2(3 times) then novus 1 and it's still hazy. I have been using a 6" buffer w/ a microfiber bonnet. Do I need to get foam is that the problem? I responded it w/ 2000 and buffed and it's better but still streaky haze, especially at top and bottom.

Yes! You will need a foam buff pad and some sort of compound/ polish... I don't know what to polish acrylic with, you're gonna need to research... Will prolly need to buff it with a compound and then again with a finishing polish...

Just think of what even the finest sandpaper would do to your car... It will leave it hazy, but that's when you use wax, to get it shiny again

Does the kind of foam matter, can I just get one to fit on my buffer? I'll get a different polisher. Thanks.

I really don't know... I was a recon guy, not an acrylic finisher 8-/ but I did used to use a bit of a harder foam for the compound, and a really soft
one for the polish, or even use an orbital buffer with a microfiber sock on it...

Buffing wheel/pad sounds like the issue. One of my favorite DIY builds on the net....

Those guys on the show "tanked" use acrylic all the time and I am sure they get scratches all the time too. Maybe do rome research on contacting them ( as I understand it they like to help people). I am sure there is a polishing compoind for resin that is out there. These guys or someone like them may put you on the right track. If you no longer see scratches, but haze instead...you are DONE sanding, so put the sand paper away. Your next step is polishing and buffing. Maybe a glass company in your area may be a good start for questions as well.
Good Luck!

I love that show! Well I went and got som plastix and that seems to work better than novus, but examining closer there are lots of micro scratches. I think that's what is causing tge cloudiness so I am going to resand the whole tank with 2000 then 3000 and see if that does it. If anyone has anymore tips I would love to hear. Thanks. Top pic is after buffing w/ plastix, you can still see cloudiness at bottom. Bottom is before.

Can i jump in!? Just sand it again and rebuff. Im a painter at a bodyshop and from time to time i have to buff my paint. Even the best of us need to buff every once in a while . when you sand you need to make sure you dont jump up to far. 600 to 1000 seems like a big jump to me. 600, 800, 1000, 1500, 2000, 3000 grit. These are the steps i would take. When sanding you need the make sure the scratches are removed as you move up. Make sure the 800 removes all the 600 scratches. 1000 removes the 800 and so on. All the way up your last grit. And when buffing just make sure you go over ever inch. The sander also make a difference too. If its not a smooth one your scratches will be more aggressive and noticeable. When i buff paint i use 1500 and 3000 grit. If the 1500 scratches aren't removed after i buff i can still see them. this may be your problem. give it a shot. Resand and Rebuff
