How do you decide when your clay bar is worn out?

Do you keep track of the number of uses and stop after a certain amount?

Do you use the 'eyeball meter'?

Would like to know what methods are used out there.:thumb:

 

i believe when u knead it, if it isnt able to show a clean surface, its time to scrap it

 

After my 5th or 6th drop on the floor I usually grab a new one

 

I use 1/4 to 1/2 a bar once on a car and that is it. Clay is cheap enough where one bar can be used about 4 times (average 200g bar) or more times so. Just kneed it every panel or so to keep it "fresh".

 

You use a lot of clay! I for one like to use smaller pieces and cut up the 3 bars of Ricardo into 3. And would find them useful for 1-2 times. In other words, cheap to clay and long lasting.

 

I rip my clay into pieces so I can throw them out, but generally speaking once the clay gets to be a darker color than originally, it's time.

 

If you get polycharged clay, you can wait until the 10th drop....:angel:

 

Eh maybe i only use 1/4 bar but I only clay one car (mine) maybe 2x a year or 3x so a bar a year is not too bad haha.

 

If you let it bake in the sun maybe 12 to promote cross-linking. :yikes:

 

What's the difference with "polycharged" clay?

 

I think Bunky was just messing around, lol, you cant polycharge clay.

 

Ohh lol. I was tricked!

 

Good point- comparing the unused and used pieces of clay is a great way to judge level of dirt in the clay.

 

Basically when the clay loses its "sheen", its done. Unless you drop it first, then its time for a new piece.
