 |
|
I need to fix about 18 inches of weatherstrip,
(the rest of the seal is firmly in place) but need to clean the old glue off the rubber. Tried Acetone, Goo Gone, paint thinner, but no luck. I understand old glue and new glue don't play well together, but don't want to buy a new seal and do it over.
What is best to remove the old glue?
What is the best adhesive to use when re-attaching? (I've heard there's something better than 3M Weatherstrip Adhesive)
Thanks

If acetone won't work, then you'll have to sand if off?

Is this 3M weatherstrip adhesive? and how old is the old adhesive? I it the black or yellow?
With the yellow weatherstrip adhesive...its really just a high quality contact cement.
If the glue is fresh...say a month...and does not have dirt and crud in it....brush on several thin coats of new weatherstrip adhesive and it "can" dissolve/reactivate the old adhesive.
What you need to clean any of these products up is 3M 08984...weatherstrip adhesive remover.
It will require usually a combination of ingredients....and acetone will never be one of them (acetone is a really specific and very crappy solvent...outside of exactly what it works well on...which is epoxies and some other plastics)
Use plenty of ventilation with this stuff and gloves gloves gloves, http://multimedia.3m.com/mws/mediawebserver?mwsId=SSSSSuUn_zu8l00x4xt9PxmxOv70k17zHvu9lxtD7SSSSSS--
It has Xylene, naptha, toluene, benzene and ethyl-benzene in it. Some other cleaners that have some of tehse ingredients and usually benzene, hexane etc,...should also work. Ray |

Yep, the old glue is hard & yellow. Pretty sure I used 3M when I put it on, in about 2003.
When I saw the price on the price on this stuff, my first thought was this stuff costs as much as a new seal. But I figure it will come in handy at new headliner time.
With some soaking and scrubbing, old glue mostly removed. 
Thanks

Please just use good ventilation and safety. This is not your average paint thinner
