Is filling holes in my car doors with Foam Insulation dangerous?
I was recently told by an auto supply dealership that I could use the foam insulation to cover the holes at the bottom of my doors in my 92 Acclaim but after reading the foam instructions it said that not to put near heat, therefore, I am worried about other problems with using this product. I do need a cheap way to hide the rust and holes at the bottom of the doors so any
other suggestions would be appreciated. Thank you.
It should work, just don’t plug up the drain holes at the bottom of the door. You might consider some of that stick-on cladding that is sometimes used on pickup trucks. It is 6 inches wide or so and can cover some pretty big holes. The chrome looks a little cheesy, but it is also available in black.
Thought about bondo its made for that and if the tail pipe is not a few inches from it it should be OK NASCAR had um catch fire but they had the exhaust pipe on that side and they drive at extreme temps. you should have no problems.
Use fiberglass for covering holes, bondo is made for small dents when it’s a hole or large dent bondo will crack.
No danger unless you get it in the door lock mechanism.
Grind the rust away till all you see is clean metal.
After foaming the holes sand the cured foam slightly lower than flush.
To cover, it is easier to use a fiberglass cloth and outdoor rated epoxy resin. No fumes and epoxy resins can be had with different cure times (5 min, 30 min, 45 min, etc..)
Since it is on the bottom of the door just use bondo, it is very easy to use, to sand, to primer and to paint.
Remember that after you are finished drill some small holes through the bondo so that the door will still drain.
