Coleman Roof Seal/Gasket

[Ka-Cee]

Hi guys - another roof seal/gasket question.  I have a 2001 Coleman Utah and have been having trouble with the roof seal for awhile now.  I have repaired it once before in several spots and am wondering if there is a magic sealant out there for this.  I have used what Coleman recommended and in other spots tried other things - still it comes apart (as in sags down in areas)... any others out there with this issue???  Thanks,

Plastics (and ABS plastic in particular) are bad for paint and adhesives to adhere to. As I understand it, goes back to the silicone based mold release agents used in the manufacture and that stuff has soaked into the plastic. Besides cleaning the surface real good by washing and then cleaning with an isopropyl alcohol, you need to then use an ahesesion promoter. The stuff I'm familar with comes in a 16oz aerosol can and you can buy it at any automotive paint store  (who knows, maybe even Wal-Mart carries it). Anyway, spray it over the surface where the adhesive is to be applies, let it dry the specified time, then apply the adhesive.
