Oh got ya. See when I think of Bondo I think of it as like a glue, or something, and not a filler. And I suppose that it wouldn't matter if the putty was white or something because you would be sanding it and painting it right?
Spot putty is awesome stuff, its $2.00 at wal-mart.
You can also mix superglue and baby powder together. Just drop some glue out on a scrap piece of plastic (NOT paper) and slowly add the baby powder untill you get a putty consistancy and add where needed. It drys pretty fast so work quickly......
I used superglue to kind of tack it in place.....Then use E-6000 on the inside of the joint, if you can.You can use this stuff other than how it says. It works without putting it on both sides and waiting 10 min.
If you can't get to the inside, superglue the whole joint.
Sintra is full of VERY small pockets and after you glue it, its over.
If its in the wrong spot, you will have to cut it off or break it off
