Stick with two part fillers and primers. There's less of a chance you'll have problems with shrinkage and blisters later on down the road.
Great point.
Non catalyzed
I had taken that into consideration when I began. It really is being used, as intended, to just fill in the voids before I apply the carbon.
most of the spot filler has been sanded away
The structural adhesive is doing all the work. The carbon and Resin will finish it off and it will never crack again
I’ll let you know how it holds up over the next decade.
