Disclaimer - I have read on other posts on headliners this project has given others less than happy results so reader/DIY beware! Going to attempt and could use any suggestions (other than cease!) how best to DIY. My foam is in PERFECT condition other than OEM vinyl not sticking? I have new materials and think foam to replace but am considering the following:
Leave old foam, using new glue and then new vinyl.
Leaving old foam, glue new 2mm foam over old MB foam then glue new vinyl. The foam was included with Vinyl when purchased.
Remove all old foam, glue new 2mm foam then glue new vinyl.
Anyways I plan to do the last option as I think that OEM foam may break up over more time. Plan to use a power drill and the edges of circular wire brush to lightly and carefully remove what can be done safely then use brass hand wire brush for final.
I heard old headliner no matter how tempting should never be used so I bought Grey MB59 vinyl headliner fabric from headliner express for about 210usd. They are in FLA but shipped from Los Angeles so I had it in a day. They sent fabric and very thin foam which appears to be about 2-3mm thick. I intend to use 3M SUPER TRIM ADHESIVE (same stuff I used on my new hood liner and Rx by Gerry). Any suggestions? Warnings?
