Garage doors before polytrol

Customer calls Polytrol “a magic product” after using it on her garage doors

We recently received an email and some photos from a very satisfied customer who has used Polytrol colour restorer to revive her badly faded powder coated aluminium garage doors. The doors are of the roller shutter variety and were installed in 1991. They are south facing and had been faded badly with some WD40 staining around the locks.

She was delighted with the success of the project and sent us some pretty glowing remarks:

We are delighted with the success of the treatment. They are now as good as new. A one litre was enough to treat these 3 doors and my neighbour’s two garage doors. It also restored his faded brown guttering back to new condition. What a magic product. We never imagined that it would be so successful at such reasonable cost.

What is Polytrol?

Polytrol is a deep penetrating oil which restores the original colour and appearance of dull or tarnished plastics, gelcoats, metals and other surfaces. It penetrates the surface, re-wetting the pigments to restore their lustre and colour which has been lost through exposure to sunlight, rain and pollution and it also gives corrosion protection.  When used on tarnished metals, it brings back the shine and gives long-term protection against corrosion. Simple to apply using a cloth or soft brush, it’s ready to wipe off in just 10 minutes!

How to apply Polytrol

To apply Polytrol, first thoroughly clean your surface and allow it to fully dry. Next apply the Polytrol with a cloth or bursh and rub into the surface, working in areas which can be treated in 10-20 minutes to ensure even coverage. Wipe off any excess Polytrol with a lint free cloth before it becomes tacky and for a shinier finish, buff the surface with a lint-free polishing cloth.

  1. I have some fading of a Garador (apparently coated/stained fibreglass – white finish on the inside – light brown on the outside) lightweight up and over garage door – about 10yrs old. It faces directly south, and fading is likely cased by sun. Two/three years ago a Garage door fitter was fitting a different make of new door to my neighbours garage – and told me that my door would look much better with a coating of WD40. Do you agree? What would you recommend?

    1. Hi there,

      We would recommend using Polytrol on your garage door – it’s perfect for this application. It won’t do anything on the inside white surface as its job is to restore the pigments but on the outside brown it will restore the original colour. If you’re concerned at all then we’d recommend purchasing a sample pot first and testing it on a small area.

      Many thanks,

  2. I have a grp double garage door in a mahogany finish which is looking a bit tired. I would like to revitalise it but am keen to ensure it remains a realistic mahogany finish, can you advise please

    1. Hi John,

      We would recommend using Polytrol on your garage door. It’s perfect for your project as it re-wets the pigments to bring out the original colour meaning you will absolutely keep your mahogany finish.

      Please let us know if you have any further questions,

  3. I used polytrol on my fibreglass double garage door that had become very faded. The results were amazing and it was restored back to a ‘like new’ imitation mahogany finish. I cannot fault the product – easy to apply with excellent results.

    1. Hi Paul,

      Always work in areas that can be completed 10-20 minutes to ensure an even appearance. If the surface absorbs the Polytrol unevenly (i.e. some matt and some shiny patches) move any surplus oil from shiny areas to matt areas.
      Wipe off any excess Polytrol with a lint free cloth before it becomes tacky. Then, if you would like a shinier finish, buff the surface with a lint-free polishing cloth.

      I hope this was helpful – please feel free to contact us again should you require any further assistance.

      All the best,

  4. Hi. Our house has a combination of aluminium and Upvc windows which are powder coated in a blue grey finish. Many are faded and dull in places due to the south facing aspect and possibly also the proximity to the coast.
    Although I’ve seen some mention of metal garage doors being successfully treated with your product, I haven’t seen any reference to aluminium window frames – so I just wanted to make sure that you think the product is suitable for this.

    1. Hi there Ian,

      It is safe to use Polytrol on aluminium and Upvc – it should only not be applied to surfaces that are white in colour.
      We would recommend purchasing our 125ml bottle and testing it on a small area first to make sure you are happy with the results before applying everywhere.

      For further information, please see our product specification sheet here: if you have any other queries, please don’t hesitate to give us a call on: 01582 592707 or email us directly at:
