How to get clean metal to paint where a mouse can't stand up..

[GHA]

in the middle of re-engining a steel boat but how to get to those impossible places with a grinder to get clean metal to slap some 2 part epoxy onto?

A lot of it is OK but a load of area is underneath angle etc, so..

Any real life experiences??

Favorite 1st coat is ameron sealer but even that likes something to stick to

If you have access to power, could you hire a small compressor and one of those small sand blasting guns? You'll need a bag of sand and you'll have to find a way of clearing it up afterwards, but some of the guns have long nozzles that are good for getting into awkward places. People like Machine Mart sell them. Pretty useless for large areas though.

Alternatively, just paint the rust (if it isn't flaky) with something that likes to stick to rust. I've had good results using stuff called POR 15 on cars. There's also a primer called Aquasteel that I've just used on some garden railings this summer. Too early to say how well it has worked, but their website claims various naval paint jobs have used it. Surface finish isn't great though. It foams like nothing on earth, so it's very had to get the bubbles to all disappear.

Sorry but my experience on a steel boat that stuff is awful.
Comes off in sheets if the metal isn't perfect.
Best first coat I've found so far if you can't get to sa2.5 is ameron sealer..

Anyone use a little pencil sand blaster type thing?
