Engine Bay GRP Lining
Posted: Mon Jun 22, 2020 12:33 pm
After a lot of prevaricating, I decided to remove the GRP lining from the engine bay.
This was of course, fitted to stop the oil and water from the engines soaking into the hull, however, years of movement in the keel structure meant the water seeps in from the outside and sits between the grp and hull.
Getting it all out is a fight, requiring at least 1600 watts of heat gun (I'm on my second), a paint scraper, a couple of screwdrivers and pliers. An angle grinder with sanding disk allows you to break the job down into smaller chunks and it is slightly easier. It's also best to start in a bad mood as I find this helps. You will definitely be in one when you've finished.
Mask, ear defenders, goggles and a haz-mat suit are also useful.
. .
Quite a lot of steam was generate by the heat gun, so it all needs to dry out before starting to clean back, prime and paint.
But in the mean time, the engine brackets and keel bolts need to come out and a crack in the central engine bearer needs dealing with...
