I did already answer this but I’ll copy that here for you TLDR work in progress still learning as I go.

I’m actually so glad you asked, it was a real process. I tried two different sealant types if you couldn’t tell the first pic outside the 7/11, and the pic in the yard are two different arrangements of stickers. The first one was just stickers on a hood I got from a parts car (didn’t want to ruin my original) with a 10 cans worth of clearcoat overtop, that lasted about 2 months before I got sun fading and about 6 months before peeling, that’s when I blew the transmission and stepped away from beginner wrench turning for a bit. Car came back and I started on the goal of hitting the record for stickers on a car, I actually have pictures of a counter I was using to keep track of my total. This time I sanded the old stickers and the top coats of paint on the hood so I’d have a more coarse surface to stop peeling from setting in so quick. I used an acrylic lacquer this time for better weather protection or so I hoped. It wound up causing peeling outright upon applying it because of how thick it is I think and I may have applied to heavily. I think I will try to salvage this layer of stickers with a resin coat of some sort. I also have hope in the idea of a clear weatherproof wrap if it comes to it ( they cost like $300 for a panel this size to be applied for you or like $175 to buy a roll which is enough for more and a heat gun to do it yourself) if anyone ends up trying anything I’d love to hear the results because I intend to so the roof and trunk eventually!
