## Customer Reviews

### ⭐⭐⭐⭐⭐ I love this product
*by P***H on 11 June 2014*

My lovely new oak windows and doors were looking a bit shabby after a year and I suspected that my builder used an interior oil to treat them, so I searched for a suitable outdoor treatment and came across this one - the price took my breath away! Well, if you are going to buy fancy oak windows and doors you have to buy the best stuff. I estimated that I would need two tins, but only bought one just in case I didn't like it - could be an expensive mistake.Well, the product arrived promptly and as soon as I started brushing it onto my windows I fell in love. Those windows which were starting to look dull and patchy suddenly shone with a golden glow; it was like I had the Midas touch. It was so easy to apply, no drips, no runs, altogether very well behaved. The sun shone and the more I painted the happier I got, it was very therapeutic and I thought, "who needs an azure pool and a drink with an umbrella in it when you can do this?". And when eventually I finished and looked down, I still had half a tin left!Once dry the surfaces felt reassuringly smooth and when it rained the water just ran off in globules. My woodwork looks great and I'm sure I have put value on my house - even the wife has started smiling at me again.There is one negative comment. It said that, once applied, the finish will last up to seven years. What? - in seven years I might be dead! I'm not waiting that long have that pleasure again - come next year I'm going to do it all over again.

### ⭐⭐⭐⭐⭐ Good product
*by C***S on 23 November 2024*

All good

### ⭐⭐⭐⭐ Great product & colour is very dark
*by R***S on 23 March 2025*

Great product to protect external wood, however be careful when using on oak. The dark colour tends to detract from natural wood grain & character
