Hi Lorna, thanks for your feedback! Per your question…a clear top coat could certainly be added. I usually don’t go that extra step as Mr. Snowman will be part of a front porch display where he’ll be plenty protected. I used stain and/or exterior paint on projects like that, but regular craft paint still holds up well. I try to keep craft projects simple and cost effective. If someone wanted to add a final protective coat, I recommend using the stuff that comes in a spray can such as Valspar ‘Project Perfect’ Top Coat or Varathane’s Spar Urethane. They are both available in gloss or matte finishes.
