AT LAST - engine bay, hoses, clips and cables all sorted, cleaned and replaced.
Problem now is unsightly (and possibly harmful) rust and paint-flaking.
Some time ago on here was a post about a spray-on product to help protect engines etc., but can't find it now.

Anybody any clues or recommendations, please?

I accept engine-bay maintenance has not been my most worthy attempt, but having got round the back I see nasty rust developing on the mounts and other iron-work.

Would something like Lanoguard help stop further corrosion, and hopefully keep the donk doing its Sterling mechanical job?

TIA
 
Thanks.
Both ActionCan and AC50 appear to leave a "protective coating" which sounds good, but I wonder if the rust already on the mounts etc will be stopped or would it progress more? Thereby storing-up more trouble for the future.
There are parts "behind and below the engine" which are impossible to get at to remove the flaking rust, but an aerosol spray would.
 
First I tried green spray paint (Volvo copy). Didn't last long, but then that was a kind of half-arsed attempt.

Tried Waxoyl, which did work to halt rust on some areas, but as the engine block gets too hot for it, it simply ran off there, so not suitable.

Then tried rust converter paint (Flag paints - cheap stuff, but excellent). This is brush applied rather than spray. Turns rust black. Lasting well almost everywhere, except in a few areas where the rust broke through after a year. Simply gave those another coating. Once it stops breaking thorugh, I figure I can just spray it over with paint again, but not too bothered about that, just wanted to stop the rust and it did that.

Spraying in situ is a crap job by the way. I used a spray mask cut from cardboard to avoid getting it all over the place, but the fumes were dense and I soon fled, only to return to switch off the bleeping gas alarms. Happier with my paintbrush!
 
Only way to stop it is to remove it entirely and paint it, only way of doing that really is sand blasting but a wire wheel on an angle grinder or drill is fairly good and you would get a few years out of that and some good paint.
Ac50 is your best bet for maintaining the problem, there is no easy option with rust and don't put waxoyl on rust all it does is trap moisture and create a nice wee environment for rot

Sadly, access makes it all but impossible to remove/sandblast/anglegrind and paint.

AC50 it is then. It sounds like a quite effective "stop-gap" and better than letting it fester away unchecked. I suppose the only answer is to remove and/or replace the whole engine, but.....!:eek:
