chassis rails and dirt

[grant69]

I cleaned out the chassis of my project on the weekend and removed several kg's of dirt from the rails. I am interested in sealing them up completely as the brake cyl will be relocated to firewall. Has anyone done this and are there any traps I should know about.

Whatever you do you must NOT make the box sections air
tight, this is a certain way to cause rapid rot so make sure
there are drain/air holes in the finished items. When you are
happy with your cleaning out then douse with Waxoyl and
close them up.
