Heat makes it more workable. Leave it out in the sun for a while or place it near a heat source, but not open flame since its flammable.

Customer Reviews

Rated 4.8 out of 5 by 4 reviewers.
Rated 5.0 out of 5.0 by Good coverage Easy to apply and has good coverage. It does what it is suppose to do. January 4, 2016
Rated 4.0 out of 5.0 by It used to be so much better The old 204 was so much better. This new stuff is runny and it cracks once it dries, the old 204 wouldn't crack even after years of being exposed to the sun. Still it is much better than the other brands. Make sure you buy a pair of gloves with it because it will get all over the place, and its very hard to remove from your hand. October 10, 2015
