Here is how I re-sticky my mats now.
1.Take a bottle of Goo Gone and spread a light coat on you mat. Let it sit for about 15 minutes.
2. Take a plastic scraper and scrape all of the sticky stuff off of your mat.
3. Scrape your whole mat and get all the gooey stuff off.
This picture shows just how much "sticky stuff" came off with just one swipe. Ick!!
Here is the mat totally scraped.
4. I use Aleenes Tack It Over and Over glue and mix 50 % Aleenes and 50 % water and then brush a thin coat of this on my mat. Let it dry about 20 minutes and do one more thin coat. Let dry for 24 hours before covering with the protective film.
As always, thanks for looking!!
