Ok, First post and reply. I too have been wondering whats/what on the two products and have purchased both based on 16oz bottles. I have completely used the WGID on a 2010 Pilot Black with perfect paint and on my second application of WGDG. I did not start using WGDS until I ran out of WGID.
WGID: Wolfgang Instant Detail Spritz
WGDG: Wolfgang Deep Gloss Spritz
Cost: (EXPENSIVE) Both WGID and WGDG are 19.99 so this is $1.24 an OZ (TIED) in comparsion to other products at .60-.70 cents an OZ or less.
Number of applications: (4 per bottle) One bottle on a midsize SUV using a Microfiber and allowing the excess within the towel spread out the product as far as possible I was able to complete 4 applications so 4 Oz at a time about 5.00 each application (TIED)
Application: (Very Easy) a pleasure to use. Wipe on and wipe off. Dont really need a two step method having one wet Microfiber and one dry to shine the paint. I have very hard water so as you can imagine on a black car on a HOT Florida day you will have waterspots, streaks, smugges you cannot avoid. Both products were able to remove any imperfections with easy and minimal effort just spray and wipe. Keep in Mind I have a solid foundation of WG3.0 and I clean my truck weekly. (TIED)
Final Results:
(SECOND PLACE) WGID: On black it brings back a shine to the paint. I feel like I am cleaning instead of protecting and it does not add anything to the look.
(WINNER) :xyxthumbs: WGDS: I feel like I am protecting the paint. This product is basically WG 3.0 in spray form. I feel it is extending the life of the WG 3.0 Foundation. It also adds a warmth and depth to the paint and seems to hide most imperfections.
Final thoughts: The only issues I have with these products is the cost. I will be moving on to other products as suggested by this post to see if there really is a similar/better product at a much cheaper price point.
