I dont have one product that I really regret buying but I have a few that I probably wouldnt buy again. In no particular order
1 - The last coat black ice. I have mix feelings about this one , I actually liked working with this product and I like the gloss. I cant speak much for durability because I kept applying sealants on top of it. My biggest beef with this product is that it is marketed as a ceramic coating and they say on their website that the application towels must be thrown out. I even used a suede applicator for the product and it never hardened after a week. So I havent use this product again because I REFUSED to throw away my towels but at the sametime I m afraid to reuse the towel. Stupid me right? ... I still have half the bottle sitting on my shelf, on the other hand the last coat 2 and the last coat amp bottles ( much biggger bottles) are almost done . Black ice is the more expensive of the products but I just refuse to discard my towels
Turtle wax ceramic spray - Another good product , but it hasnt really standout from all the sealants that I have, slowly using it here and there
collinite 845 - Hard to use , never really like the results , for all the work the results are dissapointed
turtle paste wax 75 anniversary - very excited for this product, easy to apply, water behaviour is probably the best I have seen compared to any other product that I ve used. My only complaint is that it does not have that gloss factor. I still have so much left , I may give it a try over my current ceramic lite coating before I apply another coating. I do not know how long it lasts, it was applied on my dads car, but the water behaviour on this one is something else , at least within the first week. I wouldnt buy it again based on looks , its meh .
Compounds - I bought 3 aggresive different compounds , thinking I was going to do a 3 stage correction like they do on youtube. Then I started thinking that I can not be doing these corrections yearly due to compromising the clear coat . I decided to go with a one step polish . Therefore I m stuck now , should ve just bought a small bottle of aggresive compound for spot correction .
Carpro water spot remover - I bought the 500 ml bottle together with my brother ( so 2 bottles) , it has never worked for me , my brother says it worked for him . At the end of the day my brother was right , we should ve splitted the 500ml bottle in 2 and save some money instead of buying 2 500 ml bottles. It just sits on my shelf now , I had better luck with car pro essence or eraser to remove water spot, I do not even get water spots in my car which is the worst
meguiers microfiber correction pads - They suck for me , it feels like they are damaging the paint , they get dirty fast , hard to wash . I bought 2, used them twice . If I want to use a microfiber pad , I use my uro pads which have giving me better results. I still rather use a foam pad but whenever my foam pad is not correcting, uro pads come to the rescue.
3d polishing - I bought the big bottle , will never use it all. I find its not user friendly to work with , removing is such a #####. Although last time it was used on my audi, it performed better . It did correct the paint and it worked fine with uro pads. I m not a fan , I still take meguiers ultimate compound over this one , even ultimate polish , specially if I m going to go over with car pro essence. Not the worst product but for the mone I paid for it and the expectations I had , this was not a good purchased for me
Thats about it for now . I ll probably go to my garage and find something else. Lastly , I could mention that I have giving away a lot of my sealants and polisher that I never used over the years. I always like trying something new and I m learning to buy less or smaller quantities . I m also learning to do my research before buying a product as well as trying to use what I have on the shelf now
