    Peeling/lifting dashboard - which adhesive to use?

    I'm replacing the dashboard in my current P38 project but it's peeling/lifting in a few areas.
    It's a new dashboard but it was stored in a parts warehouse for 10 odd years then in my shed for a few more.


    I was thinking of using Sikaflex or similar but there's a few different types on the market.


    Sikaflex 227 or 252 seem to be the best options from what I can find, leaning towards 252 as it appears to be a stronger option.


    Does anyone else have any thoughts on what might be best to use?

    Not sure how rigid 227 or 252 set, but with a bendable plastic like a dashboard some flexibility might be good. Sika 11fc might be a good option, and its also available in grey, not that you will see it. With any of those they are not an immediate bond so clamping overnight would be needed. When I have an adhesive quandry like this, I sometimes use two different adhesives side by side or in alternating patches, kind of insurance for one of them letting go.

    Hi

    In my experience adhesives just don't/won't mix. Whatever you decide to use, unless all of the existing "dead" adhesive is removed it will eventually cause whatever the "new" stuff is to fail prematurely.

    Cheers

    There's no adhesive at all where the dash is lifting. There's a stud along the upper edge of the SRS airbag aperture that's broken - I don't know if it was broken & resulted in the dash lifting or the other way around.


    The T Rex looks good but the video looks too much like an early morning advertorial for my liking.


    I've gone with the Sikaflax 11FC. According to the instructions, it takes an hour to set but I'm leaving it clamped for 24hrs just to be sure.
    Once the dash is in, the SRS airbag will hold it all in place anyway.

    The Sikaflex 11-FC has worked a treat on one dashboard.


    I have another to repair now but it's two ABS sections of a P38 dash. There's an upper & lower section that basically forms the demister ducting &, I assume, adds rigidity to the dash assy.


    It looks like they were hot glued together originally but that has not lasted too well. There's a few cracks & broken pieces to repair too.


    Can anyone see a problem with using 11-FC for this repair?

    Should be ok, but if there are some flat sections that are touching each other, try using some strips of VHB tape too. I think the big hardware stores (unless you have access to industry suppliers like Spandex or ATA) stock some decent 3m external grade tapes, they are usually grey - not the white foam double sided which will split over time. That should allow you to assemble to the right shape, then squeeze in beads of the 11fc polyurethane. Just make sure the surfaces are perfectly clean for the tape - use alcohol or similar. Simon
