Thanks for chiming in with your experiences
I was familiar with products of this nature, but they all seemed to imply that the "blob remover" needed to be used shortly after applying the touch up paint. Since I had no experience, I was not sure if it would have any effect on paint that had been applied months or years prior.
traintrax - if you do try a product like this, take some before/after pictures, or a video showing us how it works!!
