Sandpaper

[imported_Malachi]

I recently bought some sandpaper to work on plastic lenses (600-3,000 grit) but was wondering, how this item is typically used...is it for folks who do body work?

600 has uses ranging from body work to woodworking to polishing metallurgical samples in the lab. However I have only seen 3000 grit in auto body supply stores, so that must be its purpose.

600 would be used on lenses that are in pretty bad shape. You will need to use several grades of paper for optimal results being sure to remove ALL of the sanding marks from the previous grit or the final results won`t be that great. It`s definitely a process that has no shortcut to being done properly.

Nice write up there. Sanding to 3000 will make the sanding marks much easier to remove. Also be careful not to overheat the lens as you can warp them. I also found that the DA does an OK job of removing the sanding marks completely. They weren`t visible from certain angles but were clearly visible from others. I like em perfect.:D

Wow really good directions there. I may just do this tommorow as I already have all the products that person said was needed. Thanks for posting that link!

Hmm, you got me thinking about that heat thing...I was going to use this Kit #2 with some additional sandpaper:



Plastic Headlight Restoration (http://www.autodetailingsolutions.com/Head%20Light%20Restoration%20kit.htm)



This requires me to use a drill (rpm?). I apparently need to be really careful.

Just a footnote. Meguiars Unigrit sandpaper is better about uniform grit size than 3M and other brands.
