I am trying to work out the best material to apply under the guards of the 540 roadster to help with protecting the fibreglass from star cracking as well as an acceptable finish.
On Harrision I used a urethane sealer/adhesive to attach 5mm high density foam under the guards, then applied about 4 coats of water based stone guard, then finished of with a couple of coats of 2 pack black. It looks good and appears work as a barrier for stones.

The 540 roadster has lot more inner mudguard area to cover. Although I was going to use the same idea with the foam and stone guard I thought there might be a better way. I have been looking at the spray on ute liner material that companys like Rhino and Extreme do. This can be applied to any thickness that you require and is flexible and is touugh as nails.

There is also a DIY option like Hippo Truckliner which also is a urethane paste based protective coating.

Has anyone got any other ideas.
