Yes, bleed through is an issue, but it’s not just Candy2o as far as I’m aware. Many times people doing true fire with Solvent candies will cover each layer with Intercoat Clear, they just don’t always show it on the video. The 4040 does work pretty well, but must be left to dry well. Still, it’s another lesson learnt and that’s what it’s all about.I just had a total nightmare with Candy2o... Thought I'd share it here in case it saves anyone some pain.
I created some airbrushed art on a guitar using Createx Illustration Black and White mixed with about 25% 4030 clear base and reduced 10% with 4012.
Gave it a coat of Emerald Green Candy2o - which ended up being darker than I wanted. No fault of the candy here - just my inexperience of how deep the colour goes down.
However when I tried to spray over it with more CI white it bled through horribly, and even ended up with little spots where the paint totally failed causing blotchy islands all over the artwork. The more I tried to cover it up, the worse it got.
I now understand that you need to seal Candy2o with 4040 bleed checker if you want to subsequently spray over the top of it, I also understand the older method was to use 4004 as a sealing coat.
In my case I ended up sanding the Candy2o completely off and will continue using transparent colours instead of candy to achieve the effects I need.
This was frustrating because I'd seen loads of YouTube videos of people doing monochrome artwork and colouring it with candys, then adding more opaque colour (highlights) and adding more candies. None of them had to apply an intermediate sealer to stop the candy bleeding. Could be that different brands behave differently of course.
Anyway, YMMV but I'd recommend testing your choice of candy on some scrap before you ruin the final artwork. (Yes I should have tested it first).
