how to remove calking on fiber glass roof

We searched the archives but we cannot find a match to our request.

The issue is..we have a crack in the motorhome's roof near the tub skylight and actually need to remove and rechalk almost everything on the roof since the rig is a 2002. Therefore our problem...after so much time some of the calk is the original and hardened so just scraping with a putty knife doesn't do the job.

Will a heat gun be a reasonable tool to help soften the product to aid in removal? We are just assuming it will work but are there other tips anyone has for removing older calking?
  • Sorry on two counts...yes the finger that typed the word caulk needed a talking to!!!


    Sorry for taking so long to reply, have been busy in the workshop all weekend.

    Thanks for your replies. Yes, assumed with care the heat gun will work and may also look for the product you mentioned.

    Not sure how this stuff would work on fiberglass, but, I have used it without issues, on plastic bath tubs.
    Fiberglass is inert to most materials. I guess a user could look at the label to see if there are any warnings for different surfaces. The remover is basically a strong butyl type cleaner and water, AFAIK.

  • Your search probably depends on how you spelled 'caulk'
