Plan to make some chassis reinforcement pkates for my e46 m3, basically plates to fix to the chassis where the rear subframe mounts, I intend to use an epoxy adhesive to bond the plates to the chassis as I am worried about potential future rust issues in the box sections if welded.
i am going to make the pkates from 1.5 or 2.0mm zintec sheet, I will then coat with epoxy primer once fitted.
Few questions, how do you prep the zintec to paint with epoxy, worriued I may sand through the zinc and loose its protection, or is its protection only really meant to be to protect the steel until it is used? Should I just sand it as per tds to ensure maximum adhesion for epoxy primer and not worry about it?
I understand zintec sheet has a type of zinc plating by electrolysis, this should be fine left in place when using the epoxy adhesive to bond the plates on? No worries about it coming detached?
The epoxy adhesive is suitable for galvanised sheet so should be fine on Zintec?
Thanks
