If I dont have a stapler, would m3 77 adhesive provide a stong enough bond for the flreece on the plastic on the door panel? I tested some today and it seemed pretty strong, once the resin is added would it stregthen the bond?
thanks

I'm not sure, but you can get a staple gun at harbor freight for ~6 dollars.

It's a crap shoot. You run the risk of the resin soaking through and releasing the glue. This happened to me but it wasn't 3M, it was a similar product. For me, it didn't release enough to completely mess up the job. Once it hardened, it was solid though. The spots where it pulled away, I was able to fix with body filler after. Your job sounds a bit different than mine, though, with gluing onto plastic. That might be OK. I was gluing the fleece onto MDF.

Go buy a glue gun/sticks and have at it.

How long of staples are you trying to use as 1/4" should be plenty...

I've used 3M 77 & 90 and they both work over the plastic door pannels to hold the fleece. But every time I've done fiberglass resin over fleece it released the glue as well(in spots). So now I glue the fleece down with 3M 90, then staple aong the edges and any areas that may "bubble" if it releases. Then start brushing on resin.

what about on real hard plastic that you cant staple, like the armrest, or where the lock and window buttons are?

you let the glue dry for about an hour first .lees chance of release then

ok, but will that be srong enough in the long run as well? or will the resin start to stick the panel as well?

you scuff up the panel and drill small holes in it for the resin to stick to .it works out well that way .

are the holes like on either side of the end of the fabric? and do you put the glue in the holes as well?

the holes are drilled in the plastic where you need the resin to adhere to it . just glue the fabric around the edges try not to have very much excess fabric and stretch it well

ok, ok. and what about at parts where the fiberglass needs to lay down, like where the door panel meets the dash, should I just do the same with drilling holes and using glue?

its what needs to be done when you have the problem of the glue sticking .eventually the resin will stick ,but it cant stick to a smooth surface .

and thats why the surface should be roughed up and holes drilled correct?
