Epoxy over candy.

Will the epoxy be sufficient as a barrier over candy?

Think I've finally made a decision on what I want to do to this thing. Want to go back pearl white all over. The graphic scene has been played out for me.

If it matters, the candy is SEM candy concentrate...so it isn't a real urethane candy.

I know when RM came out with their candy....it did not matter what you put over their blue candy, nothing would keep it from bleeding through. Would go through the clear also. I don't know if they've changed it since.

Really am trying to get around from stripping this thing.
 
Sell it, there's to many hours of quality artwork there for people to enjoy. It would be a crime to tear into it. But I bet a black epoxy barrier would hold back any dye.
 
if you cant sell it and you want to paint over it. video tape spraying the epoxy over it.

Yeah, that would be one of those "you won't believe what this guy does to this car" videos. LOL
 
LOL. I can't sell it. Just can't come to part ways with it...atleast not now. That pic is when it was first completed. Over the years the candy has faded...in some spots it is almost silver. Thats the reason why I'll never use SEM candy again. It has been done for almost 5 years now.

So it has to be painted...but can't just do the same thing over again.
 
It's like magic, one of the mysteries of the world..... where does that dye go when it fades?
 
barry would be able to explain why the candy fades and i am curious what kind of clear didnt lock it down or protect it from uv?
 
It is sikkens ACIII. The problem isn't the clear...it is the candy on this one. SEM knew about it. We did another allover with the same stuff. 8 months later it comes back almost silver! For compensation they sent us more candy with their "new" formula. It is still sitting on the shelf.
 
i believe paint fails under the clear, which can make the clear peel... like an old toyota or honda... again barry is the man in this dept,
 
jeremy, it doesn't matter who makes the candy or what type it is. all the paint companies get their dyes from the same manufacturer or couple manufacturers so across the board they are all the same. just packaged by each company differently. its not going to matter if you use rm's blue or hok's or sems. they will all bleed. dye migrates with solvent. where the solvent goes so does the candy. the drier you spray the less it bleeds. if you trap solvents under clear then its going to come up into the clear layers overtime. i always let my candy set overnight before clearing. i have not had an issue with candy bleeding through clearcoat into anything on top of it in years. some colors are worse than others but dark blues are the worst. to answer your question, if you feel its going to bleed through your clear and want extra protection epoxy will be a great barrier against the candy. keep in mind you cant spray a super thin sealer coat and expect it to work. if i rememebr right hok always said a min of 2mils is required. basically i would put 2 good solid coats on. another note is that epoxy is slow and wont become a good solvent barrier until its really cured out well.
 
candy isn't an actual pigment or ground up mineral, its a dye. dye will fade easily when exposed to uv this is why a good clear is so important. it just breaks down too easily. the ones we use for automotive paint are about the mose lightfast ones that are out there so they dont fade easily but still easier than pigments. with jeremy's fading problem, sem obviously found a cheaper dye supplier and it backfired on them. the machinists layout dye i use for guide coat, that stuff is purple blue color and if i wipe down a part with it and put it outside for 1/2 hour in the summer it basically completely disappears.
