TLDR Review: Krylon Clear Coat Sealer
Verdict
This Krylon Clear Coat Sealer is easy to apply and offers decent protection for projects, especially for sealing terracotta and wood. However, its tendency to dry opaque white, crack, and flake may make it less ideal for projects where a transparent finish is crucial. If you need a truly clear, durable seal, you might want to consider a product that dries transparent and is more resistant to cracking.
- Top pro:
- Provides a reliable protective barrier, helping to preserve painted surfaces and wood projects.
