First, I applied the GUARD SCEPTRE 101P to prevent rust.

This is my idea to fix this hole cheeper.

Cardboard!

I covered them with a glass fiber cloth and hardened it with the guard scepter.

Then I applied the inside the front fender with the Rubber Chipping Black.

This is my choice “APF Aluminum Putty” by SOMAY-Q,

and I applied it to the fender.

Then flattened with a grinder.

I planned to replace the original blinker because it was unrepairable. That was really hard to remove the hole for the original blinker.

Finishing with a thin putty.
