How to remove scratches off a windshield?

Would Quixx Acrylic Scratch Remover work? My windshield is not cracked but my friend was trying to help me clean off my windshield and he accidently scratched it. Now my windshield has more than one scratch. What product should i use to get rid of the scratches??? Please help!

Question answered by apoorapothecary

If the scratch is deep enough to catch your fingernail, its too deep to fix. However, if its a light scratch, you can use a glass polish to get the scratches out. When you use it, however, do not press hard into the glass or you'll otherwise scratch it further - you need to use a lot of time, and very little pressure. The best thing to use is a polisher buff for a drill, or a small buffer with a cover suitable for the polish (refer to the polish mnfr. for the correct buff pad). Griot's and Clear View both make windshield glass polish, and both are fairly good. Another polish is "AutoGlym". Good luck!

Anyone know about microscopes?

I want to buy my wife a microscope for her birthday- she loves the idea of looking at her blood cells, little animals, etc under it. I don't mind spending up to about £500 on it, but I have no idea what makes a good microscope. Can anyone tell me what are good magnification measurements/ other specifications that will tell me that the microscope is a very good one? Thanks very much

Question answered by Gary H

Just to add to David D's excellent answer... I agree 100%, a used microscope should be perfectly adequate. If you want to see life in a rain puddle and blood cells, you need 100X magnification. You will probably see used "binocular" or "inspection" microscopes which typically have a zoom but are limited to, say, 5X to 40X and usually do not have a X-Y stage. Look for a microscope with objectives of 5X, 10X, maybe 20X and 50X or even 100X. Then, with the typical 10X eye piece, you will have magnifcations of 50X up to 500X or 1000X. Individual objectives are expensive (where a lot of the really good optics are) and they are NOT interchangable between microscope manufacturers and, sometimes, not interchangable between different models of microscope from one mnfr. Older microscopes (research or scientific) often have only one eye piece and, if she will spend many hours at the scope, two eye pieces are more comfortable to look thru but there were a whole lot of scientists looking with one eye for many years before two eye piece scopes were available. In fact, some microscopists preferred one eye peice because it allowed them to look at the sample and draw what they see at the same time. Lighting considerations... Some scopes are designed only for transparent samples (sample is between the light source and the objective) so looking at a drop of puddle water is fine but you can't see thru a leaf, for example. Some microscopes are designed only for reflected light (the light source is on the same side of the sample as the objective). This allows you to look at samples which do not transmit light, polished metal or stone samples for example (metallurgists and geologists do a lot of looking at things under microscopes). Best flexibility is a scope with both, light from below and from above (transmitted and reflected light). Another consideration... taking photos. Most newer microscopes come with a port to attach a camera. With digital cameras today, you can get very good resolution photos and get additional magnification by electronically "zooming". One other comment, try googling Zeiss Small World, an annual event where people, including amateurs, submit photomicrographs for judging. Good luck
