Product Details

Pettit Anchortech is a semi-permanent, waterproof and UV resistant adhesive sealant. Use this polyurethane hybrid marine sealant on aluminum, most metals, most plastics, glass, fiberglass, and wood.

Anchortech is quick to dry, and can be painted over in as little as 1 hour. It's fully cured after just 24 hours. The non-sag paste formula is easy to apply and tool on both horizontal and vertical seems.

Once cured, it is mold and mildew resistant, and won't shrink, crack, yellow, crumble, or break down. The 100% waterproof seal stays flexible to withstand joint expansion and contraction due to fluctuations in weather and temperature. Apply in temperatures as low as 41 degrees F!

Best caulk I have found for RV
By Drifter from Florida

Verified Purchase

This is the best caulk that I have found for use on a fiberglass RV. It has uv protection and hasn't separated or shrunk on anything I have applied it to on my RV.

Bottom Line Yes, I would recommend to a friend
