Clear coating over vinyl decals

I am working on a 79 El Camino and would like to add a checkered flag banner vinyl decal and would like to know what I must do to make the clear stick to the vinyl and also to avoid problems with the clear eating into the vinyl or the clear coat peeling in the future. I am using ureathane enamel clear coat. Any suggestions would be appreciated.

you can successfully clear over water-slide decals but not vinyl ones. Clear the car then stick on the decals. The vinyl is very stable and its gloss surface and colors will last a long time. If you want the 'part of the paint job' look for your graphics, you will need to paint it on then it can be cleared along with the rest of the paint and polished to a perfect surface. Vinyl stickers are WAY too thick to clear over successfully. Also the vinyl will expand and contract noticeably so if it had a clear coat it would crack and mess up very badly.

Willys, vinyl has come a long way in the last few years! A good cast vinyl film (i.e. Oracal 851) is only 2 mils thick. I've never seen a cast film shrink any at all. Sneaky, I'd sure want to do a test first though. Why not get an old hood or fender and try it?

Interesting. Have you tried painting over one of these? I know that NASCAR and funny cars use thin full body adhesive vinyls sheets to color their cars instead of the old $$$$$$$$$$$$ paint jobs. They don't clear them though.

I would be interested to hear if any hotrodders have successfully clear coated one of these graphics sheets.

I've done it when a customer is to cheap to spring for a decal, usually on the bedside of a truck. I haven't had one come back yet. I do scuff them with gray scotchbrite, though I don't know if it's necessary or not.

clear on vinyl

I am a trained Avery vehicle vinyl wrapper and a good cast vinyl printed with solvent or eco-solvent ink(with a laminate on it) will last a very long time. I have had no complaints from any clients with the exception of transit busses (but they get washed every single day). Just make sure you use alcohol or zylene to remove any waxes or other surface contaminates from the vehicle right before applying your decals.

clear coating over vinyl...

Clear coat over vinyl would be fine.In fact it will seal the edges, but remember if you ever take that decal off later.....remember that edge? I use a clear coat on the vinyl that goes over the windows (called frog juice). Don't stretch the vinyl into any indentations, it will look fine at first but will lift up in time.Most people here in the forums are real DITY'ers but there are tricks to putting large pieces of vinyl on a vehicle.If you need more info email me...
it should great, good luck
Brad......

Thanks

I appreciate all of the advice from my fellow rodders. I will try a few of the techniques that were recommended on some spare sheet metal first as recommended. Thanks a million!
