I've just done some repairs on my door using 3M 8115 panel adhesive.
I'm happy with the way it has come out so far.
Next step is to clean it up, epoxy prime and fill and spots.
My Question... Can you spray epoxy primer over the filler?. There is still some around the seams and I filled the screw holes with it so that will also get painted.
Thanks

 

Yes you can, screw holes would have been better filled with a fiberglass based filler. Polyester filler will absorb water from the backside.

 

Thanks for the compliments. I'll be upgrading my site soon to get rid of the pop-up ads.

 

Correction to my question.
I was asking about painting over the panel adhesive (not Filler).

My intention is to clean it up then paint with epoxy over the bare metal and the remaining adhesive. Then fill with filler, another coat of epoxy followed by high build primer.

My concern is with paint adhesion to the panel adhesive.

Thanks

 

Been a way from the board for a while. It looks like you guys are doing great. Glad to hear the adhesive is working for everyone.
One tip on flanging.
If you cut your replacement panel in an arch and cut your sheet metal on your truck in an arch, the flange tool will flange all the way around. You can't flange in a hard corner. But, you can flange a nice gentle arch.

The SEM brand epoxy can be painted over. The instruction sheet should specify one way or the other.

 

im redoing the box on my 93' 150 extened cab and im wondering to mig it or try the glue. im worried about seeing seems afterwords. how noticable will they be?

thanks, steve

 

Well, mine is still noticable, but only from about 10 feet and if you are looking for it at the right angle. Otherwise it blends in with all the other dents in the sheetmetal.

The key to bodywork is the preparation before paint. The longer you spend sanding that seam smooth the better it will look. doesn't matter if you weld or glue it, you still have to spend considerable time smoothing that seam over.

 

I use a product called Chemrex...it comes it a standard caulk tube...and it is used for bonding automotive panels...bus manufacturers use it for bonding sheetmetal. I have used it on everything from wood, to concrete, sheetmetal, fiberglass...you name it. Just be sure that you are in somewhat of a warm environment when you use it. It does not like cold when it is curing. Great stuff
