SPI clear on top of HOK UK kandys

Has anyone done a wet on wet with UV clear on top of a true HOK UK kandy or should I just stay save and stick with HOK clears?

Also, for the candy guys, is there any real difference between using the KK in some intercoat clear vs spraying the true UK kandy?
 
I've read that the KK is better because it's pure dye and you control the concentration, but I would ask JimC as he seems to be the one with the most experience with custom colors. He has helped me tremendously in the past.
 
I used the KK and Fx Kosmic Sparks mixed with SPI intercoat and created my own base. I was looking to create the Ford RR color that was MUCH cheaper. Very happy with the result.
 
I don't like HOK candy at all. It's like a top clear with dye in it, too much build up.
For a transparent candy I do use their concentrate dye in SPI clear base, more control, less build. I finish with SPI clear.
 
spi clear is fine over the uk series candies. with that said i also never use the uk series. something about the process i just dont like. its a urethane clear with dye in it so basically in one session of candy plus the regular clear you putting over it, you basically end up with around 12 coats of a urethane going down in one shot. that just doesnt sit right with me. the one plus about it though is that a catalyzed urethane is a stronger product than a basecoat is but thats about the only plus i can think of. oh i also feel uk has slightly less tendency to give you a blotchy finish but if done right a basecoat type candy will do the same. done as a basecoat with the kk mixed into the spi intercoat you can get it all on then let it sit overnight to flash then just clear the next day so you dont have trapped solvents.
 
Since switching to basecoat candy versus clearcoat candy I can say there are too many advantages for me to go back to clearcoat candy. 1 Ease of use. get a little spec in your basecoat candy it's a whole lot easier to get it out. It is also, I think, easier to control blotchy areas. 2 As I get older, I get tired before I can get sealer, multiple base coats, multiple candy coats and multiple clear on in one session. Getting it up to the clear stage and coming back the next day fresh has produced a better product for me. 3 Letting sealer, base, and base candy sit over night to flash has reduced dye back and shrinkage. 4 I find that due to less millage of buildup the end product does not chip as easily on edges like door edges with a ton of mills. Just my 0.02 and again, it usually isn't worth that....
 
Well I appreciate all of the replies! Ill just stick with the KK like I had originally planned. I already bought the intercoat anyways. What is the allowable number of coats with the intercoat and KK mix? 3? The test panels I did I used 3 coats to achieve the color we were looking for, but just for future projects I'd like to know the limits.
 
im not sure what your spraying or what color your putting it over but if your laying down your typical silver and spraying the candy to achieve color in 3 coats then your going to have a terrible blotchy finish when your done. candy needs to be put on gradually. very little color each coat. some colors blotch easier than others as well. break your procedure up into 6-12 coats depending on color. you dont need to do full 1:1 mix ratio. to keep build down you can reduce a little more.1:1.5 or so. as long as you have proper flash between coats you can just keep rolling with the coats until your done. once you have it to final color just be sure to wait overnight before you clear it. i usually dont go over silver. i will put a basecolor down that is a few shades lighter than what i want in the end. that takes half the work out of it and makes it require less candy and coats to achieve the final result. you can also mix it lighter which will give you a less blotchy finish.
 
ahhh candy orange is one of the easier ones. a gold base will work fine but you can also try taking that gold or a silver and add a bunch of kk to it to tone it a little more like the color of that candy. get it about mid way between silver and final color. will prob take quite a bit of kk to make an effect. you should be able to use less concentration in your intercoat then break your topcoat candy up into about 5-6 coats and that should make it pretty easy to spray and get a blotch free finish.
 
There isnt adhesion issues with 6 coats of intercoat? Just asking, I am new to the candy world so just trying to make this one job go as smooth as possible.

Not with SPI Intercoat, catalyzed and allowed to flash good before clear. I try to wrap up with base and candy intercoat before I quit for the day and clear first thing in the morning.
 
no problems but nice thing is if you know its a color where you have a ton of coat then you can just reduce it more so you have less build. 6 coats at a 1:1 mix is no problem. thats very thin. prob less than half the build than if it were a urethane clearcoat. just be sure to catalyze and wait overnight before you clear.
