need advise for blister in clear

[dustiamber]

Hi, I paint custom bikes (airbrush) and somtimes get repair jobs for problems in artwork. I just picked up a tank with a blister in the clear its in the middle of the artwork. The art work is not disturbed and I'd rather not have to sand it off and redo it. The only thing I can think of doing is poking a little whole in the clear, pushing the air out, then injecting it with clear and using a rubber clamp to hold it down till it drys. (if it ever drys w/ no exposure to air) Does any one have any expeience with anything like this???

That's an imaginative solution...I don't think it will yeald an invisible repair though. I doubt you'll be able to get the bubbles out of there...as for the clear, it needs air just to shead it's solvants, it hardens chemically so it will harden anyway...

You could take the bubble off, put the tank so the crater made by the blister is horisontal and then fill it with clear. I would sand the clear around it first though so you can blend in the repair. You could then airbrush a couple of coats of clear over that to blend in the repair. Then let it harden real well and sand/polish...I think that would have a better chance to work...cause if you inject clear and its not nice you will be back to square one and have to touch the artwork...

There is a possibility that the tank will develop other blisters elsewhere...if there is one...The problem that caused this one might occur elsewhere...

I have seen alot of those types of delaminations on tanks done with the shitty AutoAir water based paints...Clear lifts off that crappy basecoat...

I think I under stand what your saying, sand the blister open on one side so it sort of cups the new clear,prop tank so the open side of the blister is up, fill it let it dry and sand it down? That might just work... that is if that blister didnt take the top layer of paint up with it. Im pretty sure that the original artist uses house of kolor and not water borne. I've already done several different repairs on this bike, great art work but really bad prep.
