When the weather starts to change to colder temperatures it can make fun painting just a little more challenging. To avoid sticky spray or frosting from your fixatives or primers a quick easy method such as follows.
warm can to recommended temperature by surrounding with warm tap water. Fill under half the depth of the can.
keep shaken between use. If the can gets to warm simply remove for a time. Quick & Easy.
