Tips to apply and remove vinyl on top of vehicle that is wrapped?

No.

 

I wouldn’t do it. Keep in mind whenever you remove the 651 vinyl there is a good chance the underlying wrap will come up with it.

 

1. You put a calandered vinyl on top of a cast. Calandered vinyl shrinks more than cast. So you are in effect “pulling” on the cast vinyl with the calandered. The bubbling you are getting might just be that you wrecked the underlying wrap!

2. 651 is a PERMANENT ADHESIVE!! More that likely you will wreck the underlying wrap if you were to remove this vinyl.

if you do have to remove it. Heat Gun to warm slightly and very slowly remove the 651

 

Also......

1. How long have you been doing this? From your question it sounds like not too long. Hey not a bad thing, everyone has to learn. I’m not knocking you (or any one else for that matter)

2. Educate yourself! Calandered vs cast. Removable vs permanent etc etc etc

 

I'm not sure if I would try to use heat at all on the removal of the 651. Seems to me that heat applied to the top vinyl will likely transfer to the wrap vinyl which will likely soften the vinyl and adhesive of that vinyl as well.

 

I have pulled vinyl off of vinyl before very slowly with some heat...carefully and slowly...any signs of problems stop.

 

How do you not know a vehicle was wrapped?

 

That's correct. 651 on 651 only. Etc.

 

Yeah that's gonna pull up the wrap.
If you have to go over a wrap you have to use something with a removable adhesive like Retac.
Even with a removable wrap film the adhesive is going to want to stick to the vinyl due to it's chemistry.
It's designed to stick to the vinyl but be removable from paint or glass.
