Please explain "heat setting"

[VelvettFogg]

I understand the principle, I guess Im asking for the "recipie".

The paint I will be using from now on is Auto-Air.

Use a heat gun or better yet and cheaper, a hair dryer to assist and speed the drying time of the paint. Making sure each layer of paint is completely dry before spraying anymore is very important to the final product. Laying down paint on a wet layer can cause all kinds of problems from bad reactions to bad adhesion. Heat setting is simply flash drying the paint.

Heat it, don't cook it!

AA is best applied in very thin layers. With my heat gun set on 260 degrees, I pass it over the painted area until it's dry. This usually takes 30 seconds or less.

A hair dryer is a safer approach, so you don't dry the paint too quickly. If you dry the paint too quick, the paint will shrink and crack.

only if you put it on too heavy

only if you put it on too heavy

It will happen if there is too many coats aswell.

Your good then. The term heat setting I think more comes from airbrushing T-Shirts which a heat press or putting the shirt in the dryer for an amount of time heat sets the paint so that it can be washed without worry of paint blurring or fading or comming off. It is then set into the fabric by means of heat.

AutoAir is great paint and can be used for many surfaces. Because it's water based it dries pretty fast on its own anyhow. If you sprayed a thin coat and let it sit by itself for about 15 minutes it would be fine to spray the next layer or color. Using the hair dryer just speeds the waiting process and does help cure the paint also. The "heat setting" or "curing" of the paint does help with the durability of the paint also.
