    Has anyone successfully painted the internal plastic door liners, my Hymer door liners are yellowing. I have cleaned them but I would like to paint them white again. Any suggestions, I would prefer to brush paint but I could spray them at a push.I just need to know what brand plastics paint works.


    Thanks.
    Mike

    So are mine (yellowing). My advice would be to leave them alone. I think there is a high probability of a paint job looking like a bodge and unless you paint every bit of white plastic inside the van, the door will stick out like a sore thumb. The other sections I am thinking of are the pull-down bed under-tray and the door edging strips. Then there is the shower room which is also likely to yellow.
    I have resolved to live with it.

    I think that the yellowing is a Hymer characteristic, no idea why..

    I do agree that it's best left alone though.

    Scan through the classified ads, so many attempted 'improvements', they rarely look good !

    Plastic paint

    That's what I want to avoid a bodge job, unless someone has successfully repainted plastic I will live with it.

    You can use almost any paint by adding a plastisizer to it..

    We use two pack and acrylic

    If you google acrylic plastizer you should find what you need :thumb:

    Have a look at Zinnser BIN and 123. They will stick to anything, can be left as a finish or over coated.

    Can you not bring it back by using cream cleaner ?

    Not cream cleaner, but plastic colour restorer as used on cars may do the trick. Alternatively baking soda mixed with water to a paste and gently rubbed on may restore the colour.

    Yellowing of plastic is usually caused by UV light (sun). The plastic is breaking down.
    It is easily protected against by the manufacturer by using decent UV inhibitors in the plastic. Not doing so would save them a couple of cents per part, so there is no real excuse.

    Whether it can be painted easily, or not, really depends on what type of plastic it is.
    Polyethylene and Polypropylene and both nearly impossible for DIYers to do well. Paints will just fall off. They can be treated professionally, but that is unlikely to be an economic proposition.

    Some other plastics are easier to handle. PVC and ABS can be painted readily, but you must know what the plastic is before you start and select an appropriate paint.

    Cheers,
    Peter

    Painting plastic is easy go to your local spray paint shop and get a tin of plastic primer which you spray on first then spray with ordinary spray paint

    I've colour coded the mirrors the door handles and all my exterior vents to the white of the van ......

    Have a search on YouTube - lots of info (some good some not so good) but you might spot something worth trying before going down the painting route.

    id be a bit more cautious than that... some plastic paints well,,, car bumper and nowadays without any primer etc just straight out aerosol.. but agree with with peter, depends on the plastic..

    good on you ive had a few disasters with some plastics even with the plasticizers and plastic primers....
    hey I just took first place in the camper category at transitmania... not in the same league as you but black plastic trim and other colour coordinated plastic bits including my sat dome (which on best advice shouldn't be painted but seems to work just the same ..

    Highly recommended, I've used it before, dries in 7mins, you can paint it over literally anything, and put anything over it. Make sure the can has been properly stirred
    This is the can with the red markings not the blue! Red is spirit based, blue is water based and crap.
    Word of warning tho be well ventilated, I used it a lot and used to have a large fan pointing out the door blowing the fumes out.
    Another tip, on the top coat, (over the Zinnsser BIN 123) use a small sponge roller, it'll give you a finish similar to a spray gun

    The red BIN is shellac based. With the price of shellac going through the roof Zinnser has spent a lot of money improving the 123 and you can also get a 123 plus. These now stick to more surfaces than the BIN. I know it seems counterintuitive but I'd recommend the water based 123 for plastic with a decent quick dry eggshell over the top.

    Yeah I kinda got carried away with mine over the years , lost count how many thousands I spent ....i sold my split screen camper in 1998 and bought my first flat outright with the money lol.

    I then moved on to t25 and finally t4s and towed caravans .....then tired of the stress bought a motorhome ....just can't lose the modifying streak though :)

    you liked your vw then.. done a little work on the early engines for a mate once, best I can remember never quite stopped the oil leaks though lol

    on the cost front id be embarrassed to say what I spent putting the transit (a pill to convert anyway) together, certainly couldn't get my money back selling it as its a bit of a one off to suit my needs...
    you a mechanic by any chance??
