Review (5/5): Great product. Use once and you should be hooked.
I really love this stuff. Just a few tips. First, clean the area. I use accelerator and this stuff may not stick to it very well. You might want to use a small filter cloth to clean with alcohol first. Gun cleaning patches work wonder by the way! Secondly, use multiple coats. Two reasons. You will get full coverage this way. If you have not cleaned the area on clear plastic you will not get full coverage. Multiple coats will eventually fill the gaps and provide great coverage. Also, thicker coats seem to be easier to remove for me.
Using tape to grab the stuff seems to work very well. I have had some success with I bedding a very fine fishing filament in this stuff as a small ring. If it does not remove the entire thing, it at least loosens the surface and provides an easy break to grab and remove the rest.
This stuff makes it really easy to paint a finished model and mask off areas necessary. The results can be truly stunning.
