I order and use these products. I have been happy with them. No they are not the specialty products, however they do a good job at a great price.

I recently bought some ice wash to use on the non-show vehicles. I think it gives a really nice gloss to the paint. For the average user, these work very well. I am still a Zaino and Prima supporter for my show cars.

 

Really the costs of high quality products is not much different than off the shelf and work much better. Also the effort from my experience is lower with better products. Prima products are very easy to use.

I have not tried ICE because Epic, M21 and Hydro work so well. Also, I have not had to buy more Epic because you use so little to do the MINI.
