Ok just want to check something.... say a Mix ratio is 2:1:50%... is that 50% of a part or 50% of the total clear?

Ie which one out of the 2 following is it....

200ml Clear : 100ml Hardener : 50ml Thinners

or

200ml Clear : 100ml Hardener : 100ml Thinners

No I have disposable mixing cups... But that's not the point. they dont have every ratio on them either

Just thought too there could be a 3rd answer...

200ml Clear : 100ml Hardener : 150ml Thinner (that being 50% of the total, Clear + hardener together)

Test spray an old panel before you point the gun at your car.
My dad's garage walls were my test sheets. :)

Third answer.

The percentage of reducer is always a percentage of the combined paint and hardener.

So 2:1 plus 50% reducer would be something like 200ml clear 100ml hardener and 150ml reducer.

Cheers.

Nah my Clear says use 20-25% reducer... the 50% was just an example and was easier to show the calculators

shit 20 -25% reducer thats heaps usually 10% what brand of clear are you using? those mixing cups do have all ratios its got a.b.c.d.e. ect you will use the 2:1 bit. A clear, B hardener and 20% thinners which will be D. also if it's the first time spraying clear use a fast hardener because the slow hardenr is pissy as all f*ck and you WILL get runs everywher!

Bomber is correct with his ratio answer...

All paint manufacturers have different recommendations for their products, We have 2 different paint systems at work, one stipulates 10% and no more whereas the other systems recommends 20%, in the second system I'm using 35% just to get it to flow as well as the first 10% system!

People always carry on its not the paint its the painter.......

But not all paints are created equal....some you have to really work to get a nice result

Im using Protec clear atm and its 20%....But i have been sneaking up to 30% in it with a mix of regular and slow reducer.

I love slow reducers....mmmmm flowy :D

i just sprayed up a diff using slow hardener in the clear you are right it is flowy it sprays on nice and wet but for an inexperienced person spraying clear i wouldn't recommend it. i probably could of done using no thinners even tho it was only 10%

Agreed, if you know what you are doing it flows out so much nicer, if you dont know what your doing you wont get runs, you will get curtains.

Cheers.
