One Carb Or Two?
Posted 22 May 2013 - 08:13 PM
Hi there guys
I am trying to tidy up my engine bay at the moment, and want to tidy the block up a bit. Gonna do my best to wire brush off as much rust as possible, but if there's a bit left could I just paint over it with Hammerite Direct To Rust? How long would that last and would it flake?
Thanks

i have used brush on hammerite tons of times on engine blocks. i find it sticks really well and the finish is quite long lasting (several years)
however, its all about the preperation!
you need to get the engine, or any other bits you want to paint super clean and dry. old tooth brushes are great for getting the muck off, and you want to use something like "gunk" to spray on to get the muck off it.
i cant stress enough how important it is to get it clean. take your time and make a nice job, take as many bits off as you dare to give you access to the whole engine.
i have seen plenty bad jobs in the past and they look truly terrible, and its hard to put right afterwards.

brake cleaner is good for getting engine blocks clean and grease free.....

The other thing you will get though, is people saying because hammerite isn't 'proper' engine paint that it will burn off with the heat from the engine. But if an engine, regardless of what its been painted with is getting hot enough to burn the paint off, the type of paint would be the least of your worries.

Yep, but then I did paint the engine in the 25 with hammertie 8 years ago and despite overheating once or twice and 24k later the paint is still firmly stuck (were I haven't chipped it)
