The plastic caps on the end of our awning are deteriorating - rather like white PVC chairs that have been in the sun too long. Any suggestions on how to treat them so a) they look better, 2) they don't get worse.
Tempted for new ones - just didn't want t replace them if they can be spruced up. I've tried cutting compound, Autoglym polish etc. but the rough bit still look and feel rough and are still a little spongy. Wondering if wet and dry sandpaper would help.
A little something used in the auto trade
Remove caps.. Smother with 3 in 1 oil
Heat from the back with a decent hot air gun.
Allow to cool
The plastic goes manky cos all the oil has leached from it.
If they have not gone too far then just a blast with said hot air gun will bring them back and reseal the face, but if they are long gone you have to try and get some oil back in to the stuff.
heating will open the pores of the plastic allowing the 3 in 1 to soak in.
Have used it a few times but only with coloured plastic parts.. honest truth is I have NO idea how white plastic will react
