Hey Guys - Need some help. I was preparing to mount the canopy. I was marking my canopy with dry board markers (blue) for the braces and canopy outline. When I tried to make some corrections, this is where the trouble began. I used windex and then denatured alcohol to wipe the markings away. Needless to say, 90% came off but there is a subtle trace remaining on the canopy. Any help in fully removing the marks. Many thanks. Chic

Use car polishing wax...

Thank You for your response. Will go give that a try. Chic

I have even used "Zip Kicker" for super glues to remove markings that alcohol won't get. Then you can use plastic polish to really finish the job.

Still working - will give both techniques a try. Will keep you updated. Chic
