THANKS IN ADVANCE!

Try this:

and

Then practice using your search engines some. Pretty easy to find.

Glad to help though.

bigyellowbird... I tape and spray paint the tips and just add more
paint to the light side... Sometimes it takes me a few tries to get
it balanced... But I'm getting better at it now:-)

Plus you'll see the tip better when the engine is running....

I would not recommend sanding. Sanding could POSSIBLY weaken the blade.

You are safe by adding paint or clear coat to the light blade.
