I thought I would share how I try to pro long the life of my rc lids. Some times I will shoe goo them before I run them but they will still crack over time.
The first thing I do is drill holes on either side of the crack so I can stitch them up with wire ties.
Here you can see where I have trimmed the wire ties getting ready for the shoe goo.
This is one of the spots I have fixed awhile ago and is holding up great.
Here is where I have put shoe goo. I go very heavy with it.
I know it is not the prettiest thing to look at but it works.
