View Full Version : Removing scratches in plastic.

05-09-10, 01:48 PM
Afternoon everyone,

After some advice as to how I remove scratches in plastic? (ie door's, glovebox, boot area etc).

The father in law and I had a trip out to a cattle station shooting and when packing (in my absence) he carelessly threw stuff in the back (scratching the sides and rear door), threw rifles in the back seat (which scratched both rear doors and the centre console) and I don't know how but he managed to scratch bits of the front passenger seat at some point in time. :curse5[1]:

Anyway, we'll leave that all alone, I'm now looking at ways to remove the scratches, hopefully by way or some type of polish or similar.

Has anyone done it before or does anyone have any knowledge of how this can be achieved? I've never done it before and I'm not even sure if it can be done.... :help[1]:

Any help/advice would be much appreciated,

Gday Dazza.
Back in working for mitsubishi days doing used cars we used to call in a bloke who specialised in doing things like this. Bumpers mainly but also did interiors. He actually used a heat source to sort of melt the plastic back into shape and it wasnt fast or easy and i dont think to cheap either. Mind you this was going back a few years now, maybe some other solution out now? He was actually a paint touch up guy and also removed small dents etc on site and knew his stuff. Might be worth getting in touch with local touch up guys or even a panel beater to point you in right direction for your area.
I think its Marty on this forum works for a dealer and maybe his used car department might use someone who has a franchise up your way. Failing this you could try a local used car dealer and hit them up. Good luck with it.

Hi Dazza

It really depends on how deep the scratches are...but minor ones can be removed. If you have patience you can get rid of ones that are slightly deeper. Ones that have cut through the plastic are really hard to remove unless sanded out. Also keep a few 0000 grade sandpaper and 0000 grade steel wool handy to polish out the marks (be extra careful with the sandpaper and always wet it before you go near the plastic )
Here are a few things you will need

1. Professional Plastic Restoration System. These guys sell it and i have imported them from these guys before and it worked well. (http://www.autogeek.net/lc-plastic-pro-kit.html). A step by step guide is also included in the URL.

2. A good rubbing compound ( these are generally used to remove paint scratches however they work fab with plastic also) A good one is 3M extra cut removing compound (http://www.autogeek.net/3m-extra-cut-compound.html)

Once you do them then get a good platic gloss from armourall or any one and rub it for the bling......

hope it helps

Your father-in-law sounds a bit like my ex-wife's dad, who would just blindly throw/shove stuff in regardless, but if you scratched his car it's a different story!!! :(

I know a bloke here in Sydney that repairs rips in upholstery on cars & boats (& even repaired a leather recliner for us), but really only does soft material like leather & vinyl. You could try looking up vehicle/marine upholsterers but I think you'll have more luck if you live near the NT coast.

However for hard plastics a good product that helps 'hide' them is 'Turtle Wax 2001 Super Protectant' which is in some way is similar to Armorall but I think it lasts longer & works better.

Found this comment on the Patrol forum;
"armorall is crap - it'll crack ya dash.
I am very happy with Formula 2001 from repco stores. I've been ussing it for about 4 years now. It comes in a day-glow/hi-vis green bottle with day-glow orange writing.
And I don't work for them or the shop. I just rate the product +++
The difference I think is that armorall is silicon based and...
Formula 2001 is polyurethane based "

The Turtle Wax website says it does contain silicone, but anyway both those ingredients are irritants (but silicon is much more so), so use sparingly & leave your doors open for it to dry properly.

Cheers :)

Hi Dazza,

When we have to remove scratches from plastic trims at work i use a gas powered soldering iron with the soldering tip removed. You use the iron to gently warm/heat the plastic up and then rub it with you finger to smooth out the scratchs and repeat as needed. You dont want to get the plastic too hot as it will have a glazed look to it after you have finished.
This works on textured and smooth plastics, BUT try it on some old or unseen plastic first to get the hang of it.
