We use this product daily in our exterior cleaning business & highly recommend it's use to restore the colour to sun damaged composite colour doors (Not suitable for white doors).
 
It will arrive securely packaged along with a practical guide sheet of how we apply/use it professionally on a daily basis with great results.
 
It comes in a 125ml can & is enough to treat at least 6 standard size composite doors.
 
The product 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! It can be used on both horizontal and vertical surfaces and can even be used on fibreglass (GRP). It dries to a tough and long-lasting flexible finish which does not leave a film – so it won’t peel or flake.
UK Only -  Free P&P!
Ps: We also use this on our vans/trims/dashboards & bumpers, brings all faded uPVC back to black & lasts a long time between applications!
