Best for engine degreasing prior to repaint?

[frangar]

Im looking to tart up the JP over the winter and wondering if anyone has a miracle spray or liquid for cleaning and degreasing the engine prior to painting.... in the past I used a Rustoleum spray that you then just wiped or washed off....it went on a foam and was quite effective but they seem to have stopped doing it although they do other degreasers.

 

It would be ideal if it had a low VOC so i don't end up with a load of explosive fumes in the bilge but I realise that might be asking a fair bit. 

 

I also don't want it to leave a residue so I can put the engine paint on with minimal prep so I think that rules out stuff like Gunk etc.

 

I await the panels thoughts!

I recently tried WD40 Degreaser (one of their newer products).  It did the job, but so did paraffin the previous time.  I would always opt for solvent based products because I can't comprehend covering the engine in water based products, surely it creates rust? 

 

I can't comment on whether anything is compatible with painting as this is a "dark art".  I'm sure the painting experts will be along shortly to offer their advice.

Finishing off with panel wipe should prep the formerly greasy bits for paint whatever you use.

I use this stuff:

does exactly what it says on the plastic container, and less than nine squids a gallon!

Every car, motorbike and tractor engine gets wet without much of a problem

I guess your requirements depend how filthy the engine is.

To clean a slightly oily surface  try Elbow Grease.
