Rustproofing - battery compartment in engine bay.

quenching

Can anyone recommend an easy to apply product that I can apply to the bottom surface of the battery compartment of a Mercedes 190. I've got a new battery tray and have cleaned up a small amount of surface rust on the floor of the battery compartment and treated it with a rust convertor to catch any surface bits I might have missed, but I'd like to now coat it with something that will resist a bit of standing water. When it rains the water tends to pool in the floor of the battery compartment and I want to prevent anything serious developing.

Ideally I'd like something I can paint on with a small brush and dap into corners etc. and can pick up in a local motor factors. I don't mind having to reapply it annually. Anything from Waxoyl of any use?

How about tetrosyl brush on seam sealer ?

You could use Hammerite (Kurust) small bottle around 10 euros.
Clean area well brush on wait for it to dry on prime over.
Good stuff.

Mercedes have a comman problem with drain pipes clogging up with stuff and water can not get away and ends up flowing over in around engine bay.
And you end up with rusty areas.
Make sure your battery is not leaking or you could be back to square one again.

Once you have the area rust free this should keep it that way

There is a clear version of this too but it's more expensive.

That's exactly what I've done so far, and I do make sure to keep drain holes/bungs/pipes as clear as possible. My problem is that the car is parked on a bit of a slope and this makes it pool a bit just to the side of a drain hole.

Think I'll get some of the clear Waxoyl and use that once I've painted the area. Thanks to all for the advice, much appreciated.

drill a 3mm hole in the middle of the area where the water pools.

I would if I could determine exactly where that would drain to, I might just be moving the problem to somewhere I can't see easily. I'll take a look though, thanks.

I have quite a lot of experience of the rustproofer mentioned in it's various forms (Rust Master, Loctite, Kurust) and "Turns rust black" is a bit misleading. I've found that it actually tends to turn rust brown a lot of the time, which isn't worth a fook. You really need to strip back to bare metal, then it works wonders. It is a very good product.
