I tried to paint under my rear window. I paint only to keep repeatedly breaking through it whilst sanding. I even made up a wd40 type tube for my spray can in an attempt to flood the void with paint and give me a lot to sand back with. Nothing works. I can never flatten that paint. It’s gone on far too long now. So, I decided enough was enough. The window was coming out. Anyone know what substance/glue remover will remove the rest of this sealant? Also, what is a good sealant for refitting when I’m done? If it’s too awkward a job to refit I’ll ask a window fitter to do it. Thanks.
