Hey Accum, I am still learning the terminology so I should be careful when I use the words gloss, depth, shine, etc. I'm almost acting like I know what I'm talking about

.
The shine and gloss (similar I think, right?) were fine under most conditions but the overall look was different from the other LSPs I've tried. I think the look was a little less "wet" and deep (again, I think I know what these generally mean). I may not have properly used the finishing polish before I applied the Fk1000P - not sure, but I will try it again. I was very pleasantly surprised when I over-applied the FK to the car's rear matte black diffuser and it came out really nice! It darkened it up quite a bit and made the faded trim look great. On one other area of trim on the car, it did not work so well though but overall, I was happy about that.
I want to use a durable LSP but one that also adds to the car's looks. The current LSP I have on is a spray sealant and while it does add to the look, I'm not sure how durable it is. I do have to be honest about the FK1000P though: it felt like a substantial product and something I think would be quite durable. I will try it again not far from now.
Good to know how you use the FK1000P. With a lot of the LSPs, many people use some sort of "booster" to maintain it. I'm wondering if this sort of thing is dependent on the type of LSP used or preference by the user? Maybe both?
I've seen some nice reviews on the IUDJ by you and some others so I'm interested in the product. I would use it as a rinseless wash mainly though. I will have to look into the ABC approach - thanks for the recommendations.
Regarding the FK1000P, you have mentioned that you just leave bird droppings on the car because the product provides protection against them. This is a great quality of the product. I've had bird droppings on the car the past two days. Yesterday, there was a larger dropping so I figured I would wash it and ended up washing the whole car. Today, there was another one and I was using my hand and fingernail to sort of wipe it away. Then I realized this might not be the best way to approach it so I just poured water over it and it came off.
Thanks.
