So these are the items I use. Two that are not on here, a sponge and some very soft kitchen towel. I use micro set , micro sol and micro flat in all my decals including carbon ones. I have two tweezers from Tamiya which are my preferred make, don’t know why they just feel nice in the hand. The tray in the top is used with Luke warm water for 90 percent of my decals unless they are too big then I use an old photography developing tray. Big tip, I have come to appreciate in keeping my carbon decals true, uniformed and consistent with what I’m adding it too. Unless I see an image saying different all my decals have the impression they are one piece. To me this just looks nicer and more realistic. I use a scalpel to remove the excess clear edge to the decal. Even though I’m going to clear over it I don’t want any issues going on under the clear when the car is subjected to light over time. ( some may think poppy cock but that’s my take on it ). I use two different sizes of brush to eliminate ridges and smoothing out the decals and removing excess fluid from under Neath. A bit of towel to dab it at the end bug be careful one false move and its good bye decal.
Here are the clear coat products I use from zero paints. As a tip I would always use the same manufacturers when mixing paints etc, that’s my experience everyone is different so please don’t neglect to experiment.
I also use Alclad finishes too and Tamiya compound finishes. One thing I do use that I have recently purchased as of 2020 is a set of clay making tools. They are very soft rubber and come in 5 different styles. These aid me to manipulate any decal specifically carbon and larger area decals to their surfaces. They are very cheap and can be purchased on eBay for under £10.
These tools are so good at allowing your to adhere the carbon to the obscure edges of parts. One thing I’ve always come to realise is that no matter the surface always make sure it’s of a clean gloss surface. The decals stick so much better.
