Bests & Worsts Reviews from Amazon

First in order for this review to have any meaning you have to understand how the product creates a clear or smooth surface. As a general rule if you don’t have to rub the surface the product is not removing any material and is not a polish. There are many products that have a wipe on fluid that causes plastic such as a headlight cover to appear more clear. The surface is sanded (this is the rough polishing) to remove the oxidation and give a uniform surface. Then the chemical is applied. The chemical is not a polish. It is a chemical reaction that is melting the plastic similar to running a flame over a candle that has scratches. Solvent melting of a surface usually degrades the plastic it melts. It may appear smooth but is weaker to scratches. There are products that fill the gaps so that a surface appears more clear. Put oil on a frosted glass piece and you can then see through it. This product is in that class. There may be some polish in it but it is very little and/or very fine. We found little to no affect. Any product that is wipe on and wipe off is not polishing. Polishing takes a buffer or some elbow grease. We did not wipe on and off but used a buffing wheel. I would guess there is an optically clear filler like car wax in it and that gives the clearing affect for a limited time. To actually polish plastic you are removing material. If you have deep scratches then you would typically start with a courser polish so you don’t spend all day with a fine polish. This will scratch up the entire surface to remove material till there are no scratches deeper than what the polish makes.. The next stage is to use a finer polish which reduces the scratch depth again. You use finer polishes till you have the clarity that you want. The softer the material the more difficult it is to polish. There is no magic wipe on “polish” that we have found. If there are not different grit polishes then it is likely that it won’t work well. One of the ones we have had success with is Novus. The higher the number the courser the grit and the cloudier the surface will be without going to a lower number/finer grit afterward. 2 is not bad for optically clear but it is not water clear. If you use a buffing wheel and spin too fast and push too hard you will melt the plastic and make a real mess. A drill may be a better choice if you haven’t worked with a buffer. Pick a product that meets your needs understanding what it does and if that is the best option. It may be too thin or delicate or soft for a polish.
