I used it to spay hidden areas that were never covered in paint or primer, like under the dash, package tray etc... For those areas I used the gray encapsulator because it looks like bare steel. When I look under my dask it looks factory new. I also used it on other areas that I couldn't get completely stripped, like floor pans, inside doors. Some of those areas I sprayed over with enamel or Extreme Chassis Black, because rust encapsulator doesn't like lacquer, it tends to crack under lacquer. Overall I have been very impressed with their rust encapsulator. I even did my own test and took an old rusty piece of metal with some samll rust through holes and wire brushed one side and left the other as is, sprayed both sides with encapsulator and the topcoated with white (so I can see if it rusts better) and leaft it outside all fall, winter and summer. After all that time the only signs of rust were where the holes were and they were very small and light. Given all of the outdoor exposure, rain, snow and sun I was very impressed with the performance. All of the places I sprayed on my car look just like th eday I sprayed them, about 8 months ago.
After applying the rust encapsulator to bare metal and also to the sanded down metal, I should then apply a topcoat onto it? No primer is needed ontop of the encapsulator before topcoating?
