Removing plastic laminate

[cme4dk]

I have two patio doors with white plastic laminate on the outside, which has been coming loose due to the weather.  I already removed some of the sheets and reattached with contact cement about three  years ago, but most of the panels are now loose again.  I want to remove them and prime and paint them white.  I had no trouble removing the first white plastic panel but I am having a hard time removing the adhesive before priming.  I used mineral spirits with a putty knife but that is slow and does not remove all of the adhesive.  I used a heat gun with a putty knife and got more of the adhesive off.
Is there an easier way to do this?  And can I leave some adhesive on the wood if I prime before I paint?

Lacquer thinner should do it. Soak a rag in thinner and lay it on the adhesive for a few minutes, scrape with a putty knife and repeat as needed. Let dry and lightly sand before priming.

Some adhesives are heat activated.  You can try using a heat gun or a household iron to heat it up and see if it comes loose.

Could go on fire if you get it too hot or use a torch to heat it!  Do it outside.

The heat gun could char the wood, but a household iron is probably slower, but safe.
