Title: Mounting panels?
Post by: ShreddinPB on May 15, 2017, 08:41:09 PM
Hey guys, I am planning on mounting some panels on the roof of my 97 Winnebago Adventurer. I got the fairly standard non drilling type mounts

I also read I should use sikaflex 252 to mount them. I read that some materials need primered to work with sika 252, I looked in their primer chart and dont see fiberglass listed (I believe that is what my roof is made of)
Also, I did try to find some to order and it seems difficult to locate in time ( I plan on mounting the panels this weekend) Are there any alternatives?
Thanks!

I have some of that also, is that better than sikaflex 252?

Compere the shear psi. Iso alcohol gel coat only prep needed for direct bond.
