Odd marks in clear bra

It's Venture film. I don't think I scuffed it, but it is certainly one possibility. I was using a freshly-laundered microfiber towel at the time. What do you suggest I try?

I have seen this happen before even with fresh microfiber. This typically happens with the uncoated film... VentureShield... not the Ultra (top coated) film. Heat sometimes will "heal" fine scuffs/scratches in the uncoated film. I have used a heat gun before and had some success but you have to be very careful and know what you are doing. I have also used very fine polishing compounds on the film and worked it lightly. Usually it will polish out after a little effort but do not rush it. It does take some time to get out.

Like others have stated using a good sealant will prevent you from getting any more. Rejex works well and Zaino also works very well once its layered in. I personally use an acrylic sealant I found that is made for aircraft windscreens. Its made by LP Aeroplastics and comes in a white bottle. Its a great product and even has a fine polish in it for removing tire scuffs.

One thing to stay away from is Plexus. There have been numerous tests done that show it accelerates the yellowing process in films. It has butane in it which really dries out the film and actually burns it. So avoid that all together.
