Post Engine bay,bonnet,boot lid and arch sealer
Whats the best stuff to use to cover over the bare fibreglass inside the engine bay, under the bonnet and boot lid, is there a form of undersealer that sets solid, any help appreciated.

When i did a lot or glassfibre work on a speedboat i painted the bare fibreglass in the engine bay with resin and some proper colour tint mixed into it. I'm not sure where you'd get it from now though. I cleaned the fibreglass first with acetone and the coloured resin stuck like s**t to a blanket :wink:

Yeah I thought of that but I was more looking into the epoxy based undersealers in say matt black, that way it should hide a lot of the imperfections etc as well as giving a good hard wearing surface, I been looking at a few on the web but wanted to know what other people have used in the past.

I bought a tin of Protectakote on ebay but I haven't tried it yet. It's a rubberoid stuff that's meant for things like pick-up truck beds so it should be hard wearing. It comes in different colours and can be overpainted too.

I think these guys do the pigments to mix in resin...

For a cheap easy option, silicone garage floor paint.

Must say I've used a cheap Bituminous paint, can't remember who recommended it but it seems to do the job.
It dries to a rubbery flexible finish, supposed to reduce star cracking due to stone chips and the like.
Came from Screwfix:

Stonechip aerosol is as good as anything I find.

I've been told epoxy mastic paint is the bees knees, any experience with this product, (Stonechip aerosol is as good as anything I find) this was my initial feeling of what to use, any specific brand to use or steer clear of?
