Big window conversion

Those of you that have done it, how did you separate the top seam? I can see myself getting very irritated trying to blindly grind the spotwelds from the back side. Any tips or tricks? I do have a panel buster like this, but I’m afraid it may damage the edge I need to keep.

Re: Big window conversion

I haven't done a top, but I've drilled out lots of spots and separated panels. Drill out, air chisel/manual chisel/hammer. Straighten edge with hammer and dolly.

Re: Big window conversion

I’m very familiar with the practice, drilling this particular area isn't possible and why I’m asking about alternatives.

Re: Big window conversion

When I did mine I used a cut off wheel and cut along side of the seam then I was able to get to the spot weld with a die grinder it still wasn’t real easy but doable put the new one back using panel bond

Re: Big window conversion

This ^^^^, cut panel as close as you can to seam, and then use die grinder, there is at least 30 spot welds. You want to minimize damage to front side as you will need to panel bond to it.

Re: Big window conversion

I got real lucky as my cab was assembled late on a Friday, I only had 10ish spot welds back there actually holding. Small amount of prying and it jumped right off.
I have the panel bond and the applicator, but have never used it before. Do I wipe off any excess that squeezes out with solvent?

Thanks gentlemen.

Here's a really good tutorial. The die grinder tip above is the way to go. Use a ball shaped tip.

just use your finger to smooth it out, like caulking, and then carefully use lacquer thinner to clean edges. You will want to put a c-clamp in light to keep it in position. I plug welded down the door area.

Better to use paint thinner because lacquer thinner might take paint off. And both surfaces must be clean dry metal for the panel bond.
