Preserving Greenhouses - Tenplast
Use 303 Aerospace Protectang on greenhouses that are constructed with plastic or `Tenplast'? (a corrugated plastic material). I treat my Tenplast in both spring and fall. Clean the roof and sides - try 303 Aerospace Cleaner, for a safe, non-toxic, and ultra heavy duty cleaning - , then treat with 303 Protectant to give the greenhouse UV and weather protection. In severe winters, Tenplast will usually yellow from the sun after a couple of years. Tests show that even after 6 years treated greenhouses show no sign of yellowing.
