Durability ,great finish,less coats ,just a better product all around ### ⭐⭐⭐⭐⭐ My front door looks a dream! *by on Reviewed in the United States August 31, 2021* This product went over my newly stained fiberglass door smoothly. It was easy to apply and left the high gloss finish I wanted. It has uv protection built in and I'm hoping it holds up better than past products I've used. I'll know for sure after this winter passes. This door's stain flakes around the edges when exposed to the harsh winter sun...still holding out for a portico from my handy hubby, 😆 I haven't any complaints since it appears to do what it says it will do. ### ⭐⭐⭐⭐⭐ It’s a very good product at a good price , with great results. *by on Reviewed in the United States May 8, 2025* Easy to work with , I cut it 3 parts spar varnish to 1 part paint thinner . Three coats went on easy and thin, drying time between coats about 24 hours it seems very durable and of good quality.Cutting it down with thinner really helps and product is not as sticky. Used 00004 fine steel wool and tack cloth between coats. Be patient ,take your time and all will go smoothly. ## Frequently Bought Together - Varathane 242186H Classic Clear Oil Based Outdoor Spar 275 Voc Urethane, Quart, Semi-Gloss Finish - Pro Grade, Paint Brushes, 5-Piece, Paint Brush Set: Flat & Angle Brushes for Latex and Oil Paints, Stains, Interior & Exterior Home Improvement - 24 Pcs Foam Paint Brushes, Wood Handle Sponge Brushes for Painting, Staining, Varnishes, and DIY Craft Projects (1'', 2'' and 3'') --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/23335657-outdoor-spar-semi-gloss-urethane-oil-based-exterior-wood-protection](https://www.desertcart.us/products/23335657-outdoor-spar-semi-gloss-urethane-oil-based-exterior-wood-protection) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-20*
