the paint will crack a lot easier compare to the right mixture..
Different paints require different amounts of hardener. If there is a label on the paint it should have the ratio on that. One part hardener to the about of paint you use will usually be enough. You can't store the paint after the hardener is in it, it will set up in the can. ----- In actuality a 1:1 mixing ratio of paint to hardener (catalyst) will usually result in brittle massively overcatalyzed paint that will flake and/or chip easily. However as previous stated different paints require different amounts of hardener, alway request a Product Data Sheet (PDS) or Technical Data Sheet (TDS) from the paint manufacturer or retrieve one from their website before mixing.
Automotive paint is made up of many different colored "toners" which are essentially pure colors of paint made up of pigment, solvent and resin. These colors are mixed together to reproduce any other color. Auto paint manufacturers generate formulas which instruct the person mixing the paint of how much of each toner to add in order to reproduce the desired color. After the color is mixed in the case of basecoat it is simply reduced (thinned) with solvent. In the case of single stage paints and clear coats that color (or clear) is not only mixed with reducer but also a catalyst (hardener) to cause an interlocking process known as a chemical drying process which makes this paint resistant to other solvents and contaminants, this keeps the auto paint from ever wiping off when re-wetted with a solvent.
The term catalyst is much more general than the term hardener, since hardening is only one of endless numbers of processes which can be catalysed. A hardener, therefore, would be a specific type of catalyst.
I'm thinking of starting my own business. How much of an investment would it take to open an auto paint and body shop? How much are the average pay rates for body repair techs?
Not as much as the shape of the car but different finishes do affect drag.
Although there are some relatively cheap auto paint shops in most large cities that will repaint an auto for somewhere between $250 and $600, they are not generally the best paint jobs. A quality paint shop will probably charge between $3000 and $5000 depending on paint quality and prep work needed.
Humidity affects the drying time of paint. Paint will take much longer to dry in humid conditions. In very humid conditions the paint will not set correctly and the finish will not look as good as it should.
You can use one for the other, you just wouldn't. People generally want their cars to shine. House paint doesn't. Most house paint is latex which doesn't stick to metal real well. Car paint on houses would cost too much and soak in too much. Cheap car paint can be $50 a gallon or more and it only get more expensive.
It all depends where you go for paint job, Maaco will charge you around $1000 to $1500 for a respray., but for a real good one paint job it will goes up to $2000 to $2500 for a really nice paint job to some good auto paint shop.
A paint job will usually cost between 350 to 700$. Body repair is just a general term and the price depends upon the extent of the work needed.
Most colors are going to hold up in the heat no matter what color they are. They have a clear coat that protects the paint and it will not fade that much. The only way you can tell if your vehicle is fading is if you get into an accident and they only paint the areas that were affected.
For many paints, one gallon will cover 400 square feet. However, the quality of the paint can affect how much it will cover.
