Re: Which glue for replacing carpet on aluminum
As to getting the glue off I would try a heat gun and paint scraper, I don't think any kind of solvent will touch the glue.
And yes, I would scuff the surface really well,maybe 80 grit, certainly can't hurt.
Aluminum is funny stuff, hard to get anything to stick to it.
Sounds like you have my boat, I looked everywhere for a flat bottom jet before I bought the boat I have, have a stretch of river by the house that is too skinny for a prop drive but it doesn't have any houses on it and the fishing is great, I have to float down it now.
Good luck with the project.
