I have some down-pipes in colorbond and they have the protective plastic on them.
This plastic is bio-degradeable and as such degenerates pretty quickly.
As the plastic degrades is cracks up and sticks to the colorbond - hence my question.
As I have left the plastic on too long and it has all cracked up and stuck to the colorbond finish how do I remove it??? :?
Anyone ever done this with any success??
I tried thinners and turps on a small patch to see if that would help but no success.
piece by piece......i'd just be replacing them if I was you.

As tools say if you really want to remove it it's piece by piece. There is not really anything that will desolve it.
The good news is that if you just leave it will eventually break down and disappear over a few years (DAMHIK) other wise replace it.
I had that problem with some guttering, that I stupidly left out in the sun for a couple of weeks. Sun stuffed it.
Yep it has kinda stuffed the down-pipes.
Problem is I have larger than standard (100 x 75mm) with 100 x 150mm section size and it is as dear as poison - so not keen to replace.
I did contact Stramit where I got it from and they said "yep you have stuffed it" - try technical department of Bluescope steel where it comes from - I did and they said "yep you have stuffed it"
Can't use any solvents like turps or acetone as it stuffs the colorbond finish.
The only solution beyond the tedious is to lightly sand then paint with a sealer and paint over it all with a colorbond paint they say.
Bazza's right, it will fall off eventually
If you want it gone now!
Pick it at the edges with a trimming knife and peel it.
Get some colobond touch up paint.
Try using a water blaster on it - should get it of real quick.
Don't use solvents or thinners as they will eat into the colorbond finish and ruin it.
If you need to paint - do not use spray can paint as it will discolour within 3 months and look terrible.
Paint with producy such as Solarguard for long last.
Now the water blaster is an interesting approach - we have a couple here at work that are pretty aggressive - I'll have to give that a go. :)Quote:

I wondered about the heat gun too. Strangely it is the opposite to what the bluescope technical guy said - he recommended get the plastic cold and chip away at it.
The plastic is pretty well stuck and it has separated to something like small fish scales.
