McKanica silicone remover works well on silicone.

Try 3M General Purpose Adhesive Remover. I’ve never found anything better for 
removing adhesive goop – including the residue of 4200 and 5200. You can buy it 
at any  auto parts store that sells refinishing supplies.

 

Removing silicone is a particular problem. When I rebuilt my A hatches a few 
years ago, I sourced a purpose made silicone remover to remove the residue 
(Sikaflex won’t stick to the silicone). I can’t recall the brand I bought. 
Perhaps someone on the list can supply the name, or you can find it on a Google 
Search.

Hi All,

 

I'm replacing portlights with VHB taped acrylic. The PO sealed with Sudbury 
Elastomeric Sealant (silicon + polyurethane formulation) and screws through the 
acrylic, which  I've taken off using a multi-tool scraper.  The sealant remains 
a mess -- the heat/friction from the tool seemed to soften and smear the black 
sealant.

 

I've been trying to source some marine debond or adhesive remover that will 
play nice with fiberglass.  I did find some Xylene based Auto General Purpose 
Adhesive Cleaner (PF600) which looks promising but has a "Warning: ... not 
recommended for fiberglass..."

 

Any tips for removing the old sealant?  

 

Thanks,

 

  Jeremy

A sharp razor blade works wonders, failing that, high-speed carbide tools..
Bulk removal with chemicals is pointless.
