Removing something tigersealed in place
gaz_gaz - 29/12/18 at 12:30 PM

So I have a problem.

I tigersealed my rear carbon arch guards in place. Braced them in position and pissed off for a couple of days over Christmas.

1 of the guards has moved about 10mm while curing and now leaves a horrible cap where the guard curves to meet the body.
Does anyone know of a way to break down the PU Adhesive without wrecking the guard itself and ideally without ruining the rear arch and it's 3 stage pearl paint

Thanks

I had to clean off a carbon cycle wing covered in tiger seal. Nail varnish and warming them worked but not perfect or quickly.

Good luck sorry I didn't find a easier solution

I use this material (PU) a lot, from additional support for a battery, to bonding panels etc. Once it's cured, it's a struggle to release the substrates.

A Stanley blade can be slid between the substrates, or there's a knife thing in the kitchen (long, thin, but wide thing with beautifully rounded end) that the wife uses for something. Gentle tugging and a careful slide in.

Acetone will degrade and release the stuff, great for alloy panels or gelcoated GRP things, but not for painted wheelarches....

Methylene chloride (dichloromethane) will also do the same thing, and damage, but I suspect you won't have access to it.

Maybe some careful use of piano wire, very thin (or top E metal guitar string) ?

Still going to be s0d though

Would a hot air paint stripper gun thingy be any use? Maybe warm it up a bit before scraping?

Make a 2ft garote from some MIG wire and 2 wooden dowells. Use it like a flexible saw. It will take a while to do and you will break the wire many times, just make another one. I bonded front cycle wings with sikaflex. This was only way to remove them. stanley knife method was waste of time.

Multi tool with 25mm serrated blade. easy.

I was going to suggest this method but get some nylon fishing line instead of the mig wire to protect the paint.

Not had to un Tiger seal two parts before, but applying heat will almost certainly help. A proper heat gun will be too hot and harm the paint, but SWMBOs hair dryer can help (used my SWMBOs dryer many times to apply warmth). Once the parts are warmed then gently pull them apart. If you get the parts separated then you'll probably need to carry on warming the Tiger seal and gently rolling it of to clean the surfaces.

Best of luck.
