1: When trying to match the existing paint you can take a paint chip to Home Depot or Sherwin Williams  and ask them to match it . 
2: If you are not sure on what type of paint /primer/other materials etc to use or/and have questions on how to prepare or/and paint  first check
    with SDCPM Frazee Rep   (619) 379-7886 and email  who will meet you at the property you need to paint if needed
    and ensure that he gives you any recommendations in writing to reduce misunderstandings later.
