Repainting on old engine.

[drawp]

Short of lifting the engine out and shot-blasting it, what is the best procedure for repainting an old engine that has the paint flaking off and has patches of surface rust. I would appreciate any recommendations on preparation, priming,etc. Thanks.

I repainted mine last year and it looks fine now. Method was (all operations performed in cheap kitchen glooves)
1. put plenty of bilgex in the bottom of the bilge
2. wash engine with parafin by using a paint brush and suitable "pot" (old vitalite tub)
3. wash engine with white spirit using clean brush
4. pump out bilge immediately and re - bilgex
5. paint with light blue hammerite
the hammerite covered both paint and rust and looks fine. You may need to wire brush if its very flaky rust.

1) degrease with Gunk from the local car spares shop - it comes in a spray can - wash it off with water - I used water in a presurised garden weedkiller sprayer which helps to spray the water in all the crevices while using only minimal water.
2) remove any parts that are easy to remove to gain access, then tape over any holes
3) wire brush - a rotary one in a battery electric drill works well - use abrasive in areas the brush will not reach.
4) wipe down with cellulose thinners or Hammerite thinners
5) paint with Hammerite No.1 rust beater / primer - this is a fast drying primer that is easy to apply - no rubbing down required after
6) paint with two coats of Hammerite smooth, applying the second coat within the time limit specified on the tin to avoid rubbing down between coats. Light colours are better than dark ones.

Do consider having the engine lifted out to do a better job.

In the "oil" disposal facilty - where do you put yours?

Did you not find using Gunk left a foul chemical smell - it was nearly a year before we got rid of it on our boat after an engine cleaning session.

Not at all. It is also a safe substance as it does not harm rubber, plastic, GRP, or the environment. I used it on the engine as well as the bilge prior to painting it with bilge paint.

I use a car cleaning spray, bought at the local Halfords-type store. Spry on, let it work for 1/2 hr and then put the hose on it. Cleans out the bilge as well.

After that, rusty patches get brushed or sanded. A dremel multitool is quite handy here.

I once bought official v*lv* paint, green for obvious reasons. But apparently there are gold flakes in their mix as well, because it was a whopping 12£ for the can. Lasts me two seasons, though, and the paint sticks well and gives good cover.

A painted engine sais two things to possible buyers:
-to the novice-buyer: somebody is trying to hide something
-to the experienced buyer: somebody took care of their engine

Agree with all the above, Use to paint engines with a brush,
These days I find it far easier to use "Hammerite Smooth" which also comes
in a spray can, plus it can give a really good finish.

Thanks, guys, for the advice. I have no excuse now for not doing it!
