295UV vs 552,
Seems like this nut has been cracked, but has anyone familiar with the Sikaflex method of canopy attach inquired on the use of the 552 compound? Was thinking of giving the engineers a buzz to discuss, unless someone has already done that. Any thoughts out there?
The 552 "Areas of Application" sound a bit more applicable for canopy to frame adhesion than does the 295.
Summarizing the respective PDS:
