jeffbebe 1559 Report post Posted October 29, 2012 (edited) When I bought my car it had a knock-off ACS roof spoiler. It looked good actually but I had to remove it to replace the upper rear windscreen trim. Finally got round to putting back on using the recommended double-sided 3M automotive tape. Cleaned everything properly with alcohol, doubled up the top on the edges where the curve of the spoiler doesn't quite match that of the glass, taped it up for 24 hours, even added a couple of spots of adhesive silicon, etc etc. Long story short, I can't get the f*cking thing to stick properly. It keeps coming up at the edges. Any ideas before I lose my temper and throw it in the bin! It looks like this one on this car and fixes only to the glass: Edited October 29, 2012 by jeffbebe Quote Share this post Link to post Share on other sites
euroriffic 609 Report post Posted October 29, 2012 Had the same problem with the one on my e36, it's because it's under tension in the corners so keeps trying to lift. We urethaned my one down about 3 times before it finally stuck. I'd use that and put something rather heavy to hold it down untill it properly dries.

Trying one last gasp with marine silicone adhesive. I'll keep it taped for 24 hours to see if it holds. Failing that might try some urethane glue but had been holding off because I thought it would be an absolute pain in the ass if I needed to remove it again.

jeffbebe 1559 Report post Posted October 29, 2012 Thanks. Appreciate it Just let me know how much you want. If it falls off again I'll probably want enough cash to cover all the bloody tape and glue I've bought to try and make it stick!! haha Quote Share this post Link to post Share on other sites

Lucan 196 Report post Posted August 11, 2013 Thread-dig Wondering what you ended up using to hold this down? Have a similar spoiler in that place and some 3M VHB foam tape I was going to use but if its just going to fall off after gettting painted... Quote Share this post Link to post Share on other sites
*Glenn* 854 Report post Posted August 12, 2013 I put mine on with Eurothane.... about 3 yrs ago... It's still there and so is the tailgate spoiler done with eurothane as well. Quote Share this post Link to post Share on other sites
yng_750 247 Report post Posted August 12, 2013 i used sikaflex 227 urathane, i got it from supercheap, usually used for windscreens so is very sticky. could possibly pop down to a windscreen shop and ask them to glue it with industrial stuff Quote Share this post Link to post Share on other sites
Lucan 196 Report post Posted August 12, 2013 3M VHB foam tape 3M make a high bond strength tape for architectural / cladding use. Yepp, that's what I've got I put mine on with Eurothane.... about 3 yrs ago... It's still there and so is the tailgate spoiler done with eurothane as well. Will try the tape and if that starts showing signs of failure I'll use urethane. Cheers guys Quote Share this post Link to post Share on other sites
jeffbebe 1559 Report post Posted September 30, 2013 Tape will only work if the spoiler is an absolutely perfect fit. I used Sikaflex and urethane bond and not it's rock solid. Quote Share this post Link to post Share on other sites
Lucan 196 Report post Posted September 30, 2013 The tapes held up for a while now but its starting to lift in the corners. Needs a proper paint before nailing it done anyway, only a spray can job atm Quote Share this post Link to post Share on other sites
