Got a bottle of ACF-50 plus the atomiser all ready to spray and protect the 7's hidden tubes.
Question is, due to the atomiser/spray unit that is supplied, how large a hole is required to be made in the inner side panels to ensure good coverage and where's the best location for the holes?
TIA.

I use 1" holes, as then a 1" grommet is easy to fit into the holes...
And a 1" hole allows a good angle when spraying into the hole.

I have a couple or more along the inner panels - about seat height, and one higher up where the curved tube is that is just in front of the wheel arch.

Thanks Steve, that's pretty well exactly as I thought but was reluctant to start attacking the panels until certain.
By the bye, what method did you use to make your holes?
Cheers

I used one of those 'hole cutter' drill bits.
One that is a tapered cone.
Just make sure it's not too long before you get to the diameter hole you need
I made a pilot hole first with a normal drill bit.

Great, perforation of side panels begins tomorrow - should be quicker if it's lighter...
Thanks Steve.
