    How long does paint need to cure before it is safe to apply vinyl decals? The person we would like to use for the application (vehicle wrap specialist) says his rule of thumb is 90 days.

    What say you?

    90 is long, but a month at least. Once painted after a week, stick it in the sun to bake every day. I would go with the expert if he warranties the work.

    I'd have said 48 hours based on my paint experience with modern paint. But I've also never tried to take them off expecting to leave no trace - so there may be a gap in my knowledge base.

    If you are paying the guy you do what he says.......

    The folks at Titan say 10 to 12 days should be long enough.

    I just don’t want the decals coming off in flight.

    I may have missed the information on another thread but my questions would be.......
    1. What paint are you shooting over what primer and from which manufacturer ?
    2. What color ?
    3. Reducer....medium,hot..etc ?
    4. Flex agent added ?
    5. What environment will the painted parts be in before you try to apply graphics....cold,warm,hot,damp,dry ?
    6. What is the paint shot on....metal,fabric,plastic ?

    Each one of these factors will play a part in the amount of time it takes for any paint to fully cure......
    Remember.....being able to handle the painted parts,being able to buff & polish,having the paint fully cured are totally separate timeframes.....


    Your best bet is to find the information from the paint manufacturer.....make a few calls or send a few emails.

    PPG, base coat, clear coat (flat). The info online says if the paint is baked, it is safe the next day for vinyl. Not baked, 10 days. This is just the general info that was found. As the above states, there are many variables.

    Honestly,in my opinion.....
    With PPG base coat / clear coat...I would give it at least a solid 2 weeks of baking in the sun before I attempted to apply vinyl.
    After 2 weeks,smell the paint to see if it is still off-gassing.....EXTREMELY crude method but every little bit helps.
    You also might try pressing your fingernail into an area that is hidden and see if you leave a dent in the paint...if you do,give it more time to dry.

    Sounds good. Might wait until the 40 hours are flown off, then do the decals.

    That would be your best bet really....the more sun exposure you get on the paint the more it will dry and finally cure out.
    Paint tends to be a finicky creature....I've seen people do stuff with paint and get away with it while I know better than to even try.......lol

    This of course means lots of rolls to dry the bottom too...

    Hopefully not. We are hiring a local vehicle wrap company to do the decal application. They have experience with aircraft.

    All decals are made by Aero Graphics, in Colorado. They have a very good reputation.

    I realize the ship has sailed, but for the next guy looking for decals there’s CanMilAir up in Canada. They started by making water slide decals for plastic models then people asked for progressively larger custom jobs now today there are a bunch of Canadian warbirds flying with their vinyl. It’s neat stuff, stands up for a good long time (they’ve done a coup,e gate guards) and where the decals are on a fabric covered plane you can still see the weave of the fabric in the surface of the vinyl.
