That is the stuff! Testor's model paints sell it in the USA as "Decal Set". Thanks for the UK equivalent's name.
It wouldn't work on the methylated spirit originals, if that's what you mean.I wonder if that would work on the original transfers ?
Having painted several Vincent tanks over the last few years for members of the VOC i personally dont use water slide transfers anymore. Whist i did wet sand with 1000 grit prior to applying the transfers, i've had too many fail once the 2k lacquer (without reducer/thinner mixed in) is applied. I've found that even though when the transfer was applied and dried for 2-3 days, there appears to be no air bubbles, and then lacquering in bubbles or wrinkles appeared from nowhere. I always use vinyl decals now and build up the layers of lacquer using high solids lacquer to get the build until the decal feels almost flat to the surface.
2K = 2 part i.e. Product (ClearCost) + HardnerSadly, my latest effort ended up the same - full week before applying decals, used Solvaset dope to affix, let dry another 2-3 days, then 1 light coat urethane clear, let set up and the then final 2 coats. Looked great for about 2 days, then as you say the bubbles started and does not look good now.
I wondering about using the gold leaf size as an adhesive first. But I am still thinking the decal material itself is reacting to the paint.
Where do you source the vinyl decals?
I am not sure what 2K is - here in Canada/USA we 2 part urethane clears are the typical
