bondo or epoxy

You'll hafta grind it down & see just how deep/thick it is, because you can't decide on what it will take to fix it.

And no, you cannot just slap more bondo or exopy on & expect it to be fixed good. That is just a recipe for it popping out within 6 months.

Grind it down, Cut out the cancer and weld in a patch. That piece is structural...

Yes pull the glass. Otherwise you won't know if there is additional damage under there.

i assumed he knew what to do before just slapping it in

I have been looking for an excuse to buy a welder anyways. as i delve deeper into this car im finding serious issues under the t-top gaskets.

The A pillers are filled with foam from the factory.
The foam holds moisture and usually rots from the
inside out.

Grind and cut out the rust, braze in a new metal patch or just bondo or lead over the hole.

z28romance

foam...lol. WTF was the general thinking. i love the 80s but sometimes i have to wonder. oh well, a grinding i will go.

Over the last 20 years I have patched this same spot a few times. The last time we pulled all the foam out (IMO it is the main problem). We also spayed the entire inside of the pillar with chassis saver.

i might be wrong, but it looks like there is body filler already on the a-pillar. is this factory? i wouldn't think so. but you never know, they did put FOAM in the a-pillar.

I believe it was for sound deadening. The only reason it would cause a problem would be due to water seeping into the a-pillar from somewhere else. Since it's a t-top car I'd suspect a rusted seam or hole higher up, possibly hidden beneath a weather strip. Removing the windshield is a good idea, chances are theres some rust somewhere around the window channel. With that kind of rot at the a-pillar I'd take a good look at the floor pans, spare tire well, around the rear window, under the rear bumper cover, ground fx (pinch welds and fender drain area) post more pics if u can, a welder is a good investment with our cars

welder is a definite must. this particular hole, according to the PO, was caused by a truck backing in to the mirror and snapping it off into the a pillar. is this the truth? i don't know.
