My mate has a red Civic TypeR that has protection film on it and he wants a detail done by me. Is there anything i need to be doing when i machine polish the car or can my PC run over the film with no damage to it?
You should be fine...
I had my car machine polished and tried a few compounds...so I'll cut and paste the details:
"The Defendall Paint Protection Film (Half way up the front wings and front compartment cover, front bumper, front splitter, sills, halfway up the rear quarters ad behind each wheel arch) was polished using Blackfire Gloss Enhancing Polish using 4 Lake Country CCS polishing pads.
We tried several passes were carried out to remove the swirls, but this had little effect, and light swirling, water marks and some abrasions were still evident.
So, we switched to Menzerna 106FA Final Finish again using 4 Lake Country CCS light cut pads, and had better success with this product.
several passes were carried out to remove the swirls.
Blackfire Gloss Enhancing Polish using 4 Lake Country CCS polishing pads were then used as a final polishing stage"
Basically, try something mild to start with - like the Blackfire Gloss Enhancing Polish and if that barely touches it...go a stage more aggressive - in my case the Menzerna 106FA Final Finish.
Mine came up a treat...with a shine almost as good as the paint.
You don't need any special preparation...just try to keep the compounds away from the edges as much as you can to avoid the 'line'.
