Leaking roof bolt - Sprinter-Forum

Sprinter31 · 08-02-2012, 08:55 AM

During last rain I found water dripping from a bolt protruding inside van, just above the rear door. Bolt is there from ambo lights fixtures on the rear side of roof. I plan to use Sikaflex 252 from outside after cleaning the remains of old adhesive around light fixture. Is it the right stuff or may be overkill? Thanks in advance for your advice.

221 is the better way to go as to choice of colors , it also has high adhesion to alternate composites flexing in either direction it's water proof, longer lasting.'however' 252 is for a higher rated fixed position, it's OK! but lacks the same flexibility as 221. of which was the better product to use in the longer term .

If you already have 252 you might as well use it. If you have not got any then 221 or 291 is also Ok. I'm not sure which is more cost effective but they will all do the same job.

I couldn't find Sikaflex 221 in white color, there was black only. 291 wasn't available. I settled for 252, it was $28 (about $8 dear than 221). Thanks for the advice.
