So I was painting my Flash Gordon cabinet yesterday.

I used Rustoleum primer. I then used Molotow traffic red as the base color. https://www.jacksonsart.com/en-us/molotow-belton-premium-spray-paint-400ml-traffic-red-transparent-239-ship-by-road-only Seems like a really good paint to me.

No issues at all.

I used Rustoleum 2x Primer & Paint Gloss black for my black, again things turned out and looked great, I let it sit for 5 days......and then the gold.

I used Molotow Gold Dollar...it looks amazing where it only goes over the red, but where it overlaps black on the head stencil, which fortunately is mostly just on the word Bally, it has had some reaction as you can see here on the first side I painted. The reaction happened almost immediately as it was painted and not over the course of drying. I basically sprayed and pulled the stencil instantly and it was crackling while I was doing this.

Since I had already applied the stencils to both sides and I was worried about leaving the stencil on too long and pulling more of my paint from the cabinet I decided to sand the black overlapping areas that were visible before doing the second side. This did seem to help, but not completely eliminate my issues.

At this point I was quite upset and annoyed not fully understanding why this would happen. I took a spare 2x4 I had in the garage and sanded it smooth to match the outside of the cabinet. I primed it, an hour later I painted it with the Rustoleum black. I let that dry for about 4 hours and then I sanded half the black area and the other area I left just normal and I sprayed my gold over it expecting it to look good where sanded and to crackle on the gloss areas...instead it all looks fine. WTF?! The end of the board was the sanded area, and moving down towards the middle was the gloss. Yes I sprayed it on heavy in the gloss area as well because someone proposed that perhaps I had sprayed too heavy on the stencil which caused the cracking.

So now before I do the bottom of the cabinet I'm looking for advice. I love this gold color from Molotow, but I don't want cracking over the much larger overlapped areas of the body of the cabinet.

Was it the amount of time between doing the black and the gold that caused the issue? Is it the brands of paint not getting along (even though the instructions for Molotow cites "Belton spraypaints can be used on any surface, in all weathers (down to a minimum of -10°C), and can be combined with acrylic paint, oil pastels or markers."). I have black spray paint from Molotow (Tar Black) as well but it is very flat and I prefer the glossy look of the Rustoleum. My test board still looked fine as of this morning, do I only let the black sit for a day before I apply the gold? Switch brands?

I only have the red base on the lower cabinet at this time so I still have a lot of options just looking for best explanation for what happened and tips moving forward. Thank you.

And this is the overall outcome by the way...it still looks good, just not perfect, and again I'm worried because there is a lot more overlap on the body of the cabinet.

How would the not spraying soon enough part impact it? I did wait 5 days between coats and I was wondering if that could be the issue somehow.

My concern was if I went too soon then the stencil for the gold color would pull the black paint off.

Thanks for all the replies everyone
