Replacing Running Light and License Plate Holder - Basic Questions

[Dawn Michelle]

Afternoon all - I need to tackle replacing/repairing a side light and a license plate holder that came loose during Juno's trip over.  Two basic questions.  

1. What is the sealant used between the item and the side of the rv (aluminum)?  It doesn't look like caulk.  More like a sheet of something. But it's crumbled and needs to be replaced whether or not I replace the items-and the replacements I've found on Amazon don't seem to have whatever that stuff is with it.

2. Another issue is several screws came out and are now too loose to reattach - I 'assume' that I need to redrill (carefully) to take a slightly bigger screw - or is there a better way to handle that situation?

Excellent advice Rich,,, didnt even think about the hole size in the fixture, and that toothpick and glue sounds like a good idea,,,, I lernt something new,,

Agreed!  Good advice.  I don't want to have to deal with replacing the marker light if I don't have to (although sooner or later I'll be doing it).

This is a good way to shore up a worn hole in wood.  Have done this several times and was able have a secure hold.
