The Science behind Hard / Soft Auto Paint
Hard and Soft Paints
One of the most often asked questions; "What polish / pad combination should I use to remove scratches?" There are far too many variables to state this accurately.
Diagnosis is the key, not guess work; (see Test Panel Area) before deciding on what products to use ascertain the paint surface conditions and your goals for the paint finish. And then proceed with the least abrasive product / pad combination
Differing density (hardness) of paints react differently to correction, so before beginning to polish measure the paint thickness (PTG) panel by panel to ensure that you do not select an aggressive polish that will remove too much clear coat
Compiling a chart that lists the consistency of automotive paint can only at best be a rough guide, as this would necessitate listing by; manufacturer, OEM assembly plant, model year, colour, new or aged, paint specification, and etc.
To ascertain paint hardness requires extensive experience working on a wide range of vehicles to have a point of reference.
Identical vehicles of the same make and model/year can react very differently to compounds/polishes/etc. There are too many variables (paint spec, curing method, paint age, etc.)
Paint
Paint is a liquid, but as it dries it becomes a solid and a gas (the solvent) that evaporates, leaving behind the solid. The three primary type of ingredients found in all paints are (1) Binder (film former) (2) Vehicle (solvent) (3) Solutes (pigment). The binder is the film-forming component of paint, it imparts properties such as gloss, durability, flexibility, and toughness.
Many binders are too thick to be applied and must be thinned. The thinner is also called the vehicle, because it makes it possible to transfer the binder to the surface. The pigment provides the paint with colour. Some paints form by solvent evaporation only, but most rely on cross-linking processes
