    Our 5 year old van's appearance is somewhat let down by a very yellow gas barbecue point. Is there an easy way to restore these short of replacement?

    As an aside, why the feck are manufacturers using non-UV stable plastics?? It's not like it's rocket science to make UV stable ones. All the other components on my van are fine but the gas point sticks out like an old rotten tooth.

    As far as I know, you can't restore yellowed plastic. You can of course, replace the component but a new one will probably yellow as well if it is an 'off the shelf' item.
    Not as bad as having painted all the internal wood work in our home with Dulux white gloss only to find several years later when you come to touch up it's gone yellow and you have to repaint the lot!!:cry:

    Best to replace it. .. when the plastic degrades it also gets brittle..

    maybe try a different manufacturer and ask if they use non degrading plastic.. ?

    The phrase "not fit for purpose" comes to mind. I wonder if anyone's successfully claimed against a manufacturer for a free replacement?

    It'll probably come to that but I don't think it's so brittle it needs replacing yet, it's just unsightly. It's just a poor show that's it's happening so quickly. Smacks of a "couldn't care less" attitude by manufacturers.

    I would check out the manufacturer's warranty. I've just found that my yellow gas point is British made (unlike all the white flaps which are German). Bullfinch, the makers have a five year warranty on gas points (which mine is just outside alas). I've asked them if I need to buy German if I want a UV stable gas point. Who knows, maybe I can shame them into replacing it anyway. ;-)

    Darn, it looks like their guarantee is only for 1 year on gas points. :-(

    "Bullfinch manufactured products are guaranteed for 5 years against faulty components and workmanship. This guarantee covers the cost of replacement parts and labour in our factory. It does not cover normal wear and tear, misuse of or tampering with the product by the user. We accept no responsibility for costs incurred as a result of works done by the customer, or a third party, or consequential damage or loss.

    A one year guarantee applies to the following products:

    Marquee heaters
    Cooker hotplates
    Outdoor Utility Points
    Cabinet and wall mounted heaters
    Remington and other fan assisted heaters
    Products in our Extra Range
    "

    I would still complain to them though. It's just not good enough. As a nation I don't think we complain enough about stuff like this.

    Tesco cream cleaner and a "non-stick" scourer made our plastics slightly less yellow: NO LIABILTIY accepted for ANY problems caused by ANYONE doing ANYTHING similar - Gordon

    I painted all the off-colour plastic mouldings with aerosol enamel paint. Most of the items were 19 years old and after a quick wash, accepted the paint without further preparation.

    I did the same with an awning light canopy and cooker vent. You'd never know the difference from original.

    GRP can sometimes be brought back white as it is sometimes only the surface that is damaged sometimes by UV and often by people using incorrect cleaners and polishes that have solvents and/ammonia. A good GRP polish wont smell of ammonia. I was always told to avoid Tcut as it contains ammonia.
    I sell GRP polish on ebay and at shows and get great feedback (other brands are available) See http://www.ebay.co.uk/itm/High-Glos...tEquipment_Accessories_SM&hash=item1c4103007f

    If anyone does want any I will offer a 10% funsters discount but please PM me dont buy on ebay as it goes straight to the checkout and wont allow discount.

    I tried a bit of T-cut but it barely made any difference. Anyhow, Bullfinch are sending me a new one gratis.

    For those that don't get a free replacement, painting is a good option, the best paint I can recommend is manufactured by Sem and is designed for application on plastics, it usually has an adhesion aid product within the paint which is fade resistant and durable.
