I must say I love 100% Clear Silicone for gluing pens to my car, and I especially love it when its donated by the awesome folks over at Sebastopol Hardware Center. As gas prices go up so does the price of other petroleum products such as Silicone but the price of their Ace brand is holding nicely at around $4.99 a tube. The stuff is really good for holding pens on the Mercedes pens for around two years and then its time to put fresh ones. The constant beating of UV, heat and rain on the car really does a number on the pens but with a fresh batch of silicone it will allow me to glue more pens at City Kids Festival, Saturday August 23, 2008 – Julliard Park. Art Car Fest is also just around the corner during the last weekend in September 25-28, 2008 so I only have two more moths to figure out how and where to attach four thousand more pens.
