putting the cowl back on with no leaks

Garage is all put back together and I've started back on the cowl. Inside it's all welded and leak proof.

When I drilled through the spot welds to remove cowl I went through all the way . I'm going through welding each and every hole but I'm worried they will leak. I have weld through primer ready for the edges but I just want this thing put back with no leaks.

Whats the proper method of putting this thing back on? Where does the seam sealer go? Do you think the mating surface will leak where I'm welding?

 

BTW heres a picture of the holes that I'm welding back, all the way around from bottom to window ledge

I'm mainly worried about the welds near the window ledge, shouldnt the gasket from window etc keep the water away from this area?

 

try using 3m panel bond adhesive, it costs a little, but no welding, plus it also acts as a sealer, and no further corrosion from welding. I think that is how I would do mine if I had to.

 

that's what i used on my cowl...

we've got some of the panel bonding adhesive that is designed to spot weld through that might work well for that as well. I can try and get the number tomorrow if you're interested.

 

Thats what I would use. I cant tell you how many different things I've repaired and fixed with that stuff. Even my dining rooms chairs.LOL.

 

I looked into the 3m adhesive and that sounds like the right choice thanks for the help. :Handshake

I will continue welding the holes and painting the surface and just coat the entire outer area with the 3m and place the cowl on.

How far will a bottle of the adhesive go? Will I need several bottles for the job?

 

One tube will do the trick, however, you may try and borrow the "gun" that is needed for the adhesive. It delivers the correct amount, they are big bucks, so check a body shop to see if they will let you borrow it. I would let you use mine if you were around here

 

Nice work on that cowl. Was it a DIY job or pro/body shop? Looks like the vent slots have been sealed? I like it. Im sure I will have to get into mine at some point. I like th adhesive method -- I don't have a lot of confidence in weld-thru primer. JMO
BTW -- Is it possible to do that job w/o engine removal?

 

pic #4...see Effie doing it...

 

I was about to say, don't you mean that's what "Effie used" on your cowl... LOL I think Effie is the one that really does most of the work on Patches. Frank is always "having a large time" and back and forth to the parts store with his buddies and every time we see a picture of work being done to Patches there is Effie working away? Jeez Frank if you are going to put up a front like you do the work at least get someone else to take the pictures and pose in them like you are doing something once in awhile.... hahahaha

Just Kidding of course.

 

I was recommending the structural adhesive, not primer.

It's the same stuff the OEM's use to put cars together currently. It has the ability to support spot welding through the panels that are sandwiched together while still sealing the seam.

 

Had to resurrect my old post .

Can the 3m adhesive bond painted surfaces or does it have to be bare metal on metal?

thanks

 

It must be bare metal to bare metal.

 

alright, thank you
