YEAH!!! Welcome man! We are glad you re-discovered some new aspect of 40k! HA!
Do not worry... THE best thing about skirmish is that since the number of models is small, you can use it to re-learn to paint. Please do not be discouraged! Visit the Dipping Tutorial... you CAN have great painted models in no time! You may not win any Golden Daemons, but your models will indeed turn heads!
Check out these Terminators that I dipped... easy as cake!
If you post your pics, we will do whatever we can to give you nice pointers. Do NOT be discouraged! It takes some time to learn... but now IS the best time. Your fighters will become unique, so you can indeed paint them.
Welcome... if there is ANYTHING you want to share (PICTURES!!!), suggestions, questions... we are here to serve. Remember that
is YOUR game too!
