Well as much as I tried, I can't bring myself to continue using the TC line of products.

In it's defense, it does apply & remove easy, & that was it.
I did like the various MF towels & applicator pad & will buy more of those as needed.

The other things I didn't like:

It leaves a residue, both the TC-3 & TC-5.
TC-5 is hazy, even on the car & dries too quickly.
I found myself many times going back over the car to removed dried TC-5 redsidue spots.
TC-15 slings, rtakes forever to dry & it wears out to quickly for my liking.
The TC-15 seems to work good, but I'm still selling what I have left.

The samples of the tire clean & tire gloss I got didn't impress me either.

I don't feel TC is durable & lasts long as evident by the 2 hours it took me to clean up for a show a couple of weeks ago.
BTW, I had very recently, like the week previous applied 3 coats of TC to the car so it should have taken me like 15-20 mins to just mist it & clean up.

An experienced detailer also told me that I had no polish on the car as evident by my before & after CnR pictures.

So I'm selling my left over TC products & switching back to Zaino.

I have:
TC-3: 1 bottle with 60% or so remaining.
TC-5: 2 full bottles & 33% or so remaining in the 3rd bottle.
TC-8: 90% or so remaining.
TC-15: 80% or so remaining.
Pics of the TC I have left is here: TC products

On the bottles with partials you can see where the product line is via the red rubber bands I put on the bottles.

I feel $45 shipped anywhere in the US, no lower so don't ask, is a very fair price for what I have.
