How to recover door inserts?

Iv been working in car audio at a shop for about 6 months now , we do alot of custom work but one thing Id like to start doing is recovering door inserts with sude and vinyle and such. most newer cars have little plastic welds holding the inserts on, is there an easy way to get them off and put them back on????

Thanks,

Josh

I have had to use many  methods plus the mentioned above depending on the job.  Small pop rivets in the original holes that the plasic welds ripped through.  Drill both pieces out if you must.  Keepin mind, there may sometimes be a small issue of the rivet not being flat enough after its popped, therefore you bring out the good old hammer and lightly flatten it a little at a time.  Be sure to drill out the hole even larger than the rivet, it prevents the plastic from splitting.

Also used a pneumatic plastic injecting gun (it heats a tip like a solder iron and injects plastic like a syringe, you stick the tip in the plastic so that it melts the original plastic - then you pull the trigger while you lift the needle to fill the void).

And like everyone else, just simple small pan-head shorty screws.  I even have used a staple gun like some post offices use to assemble cardboard cartons. 

BUT, nothing works as good as throwing a perfectly good boring factory interior panels away and fabricate exactly what you want.

I once tore a door apart to reform and re-design a new set of door panels.  A previous shop drilled holes to thread some wire zip ties to fasten the door panel sections.....Please do not do this!
