Should I scratch my rosin?

Not unless you need to remove a damaged piece of a piece of vinyl in a specific way (such as to clean out an adhesive) or because you think the scratches are causing a failure in the seal. A very small amount of rubbing alcohol or any other chemical that will leave a chemical residue when applied to vinyl will help.

Are there any chemicals that I should avoid?

Some people apply paint strippers to vinyl to prevent scratching, but it’s usually not needed and can damage the paint in the process. As an alternative, try applying a very small amount of acetone (common household household item) to your vinyl and then wait 10-15 minutes to see if it scratches. If it doesn’t, it doesn’t; if it does, a solution of acetone or acetone/water diluted to a ratio of 0.5% (the ratio of water to acetone in an acetone/water tank) will probably scratch, leaving a slightly oily film. If it can’t scratch it, then a layer of spray adhesive over the scratches may help. It’s best to use acetone or a similar liquid for more serious scratch issues.

Will I be getting any sort of rash?

There is no definitive testing that is available to tell you if the effects of the chemical will occur. When a product is used on vinyl, the chemical will be absorbed through the vinyl surface for a few hours. The chemical will not migrate out through your skin or clothing, but if it is rubbed or rubbed hard enough then the chemical could cause irritation or a rash. In fact some chemicals can trigger certain skin reactions, so only use it under the most minimal of circumstances.

When doing research into all of these chemicals I have found some surprising things. Chemicals in paint strippers are not really considered “chemicals;” they aren’t classified as such in some places. In fact they really aren’t all compounds for many cosmetic and household chemicals; these are commonly referred to as “chemicals” or “solvents”. Chemicals are often the “baddies” in cosmetics/waxes/etc. and they should be regulated and regulated closely. For this reason, chemicals have been classified with the EPA as chemicals and other chemicals have been classified under the FDA as a cosmetic. (You should be able to order the EPA listing for the chemicals you’re using at your local drugstore:
