New & old holes in Chassis
May I add something to all the good info that's been posted on this thread?
First, when you remove old screws...be sure you fill the old hole with Vulchem to prevent any 'transmitted' water leaks.
* Just fill the hole with a fingertip of the Vulchem and wipe off the excess with the same fingertip.*
If your new rivet will go in the same (old) hole.......OR if you have to predrill a hole for the rivet---fill the hole with Vulchem first and follow the (*steps*) above...then rivet right into the 'wiped-off' Vulchem.
This will assure you have no gaps/spaces left beyond what the rivet takes up in the old or pre-drilled hole, and by using Vulchem, you know that 'down the pike' it won't crack and chip away from movement of the rig.
This advise is via Steve H. at AirstreamDreamsDOTcom..outlet for Vulchem.
(this is not an advertisement....just good advise, tried and true).
I actually have a major complaint about Vulchum...and that is why don't they provide it in different sizes..? since once the tube is opened ... it can't be saved. So, if you only have a small job, you're going to waste a WHOLE big tube! Doing this might not be as profitable for them......but if they sold more (sizes)...they'd make more profits in volume. Anyhow...Vulchem is a GREAT product...especially for Airstreams since it comes in a Grey colour.
