i had a similar problem back in the day and i contacted wrapsol support. they first told me that i could order a warranty replacement, but also suggested a fix: take the film off carefully and use the adhesive side of some scotch tape to "pull off" the dust particles from the adhesive side of the wrapsol. once all the dust was off, i just reapplied.
i did this and it worked great! but you may also want to just get a replacement from them
