Which is better? a Polymer Microdot or Metal Microdot?
This would depend on the application.
Polymer Microdots: Are typically used on all assets as they are non-conductive and extremely safe in all situations.
Metal Microdots: are typically used on assets that are not of an electronic or electric nature due to conductivity issues. It is not recommended to use metal microdots on motor vehicles, laptop computers, sound systems etc. and especially not if it is dispensed in an aerosol can!
