After doing some background reading, here is what seems to be the proper order for rust issues (We have a lot of heavy rust- manifolds, engine block are primary, but it is pretty much everywhere- power booster and master cylinder, exhaust you name it.)…Can you tell me if this is correct?
1- Grease removal (metal wash)
2- De rust (oxisolv/ brush)
The questions in particular are:
-Which Oxisolv is better- the gel or liquid for these applications?
-Do we need to PRE prior to RE or is this if we go from 2 to 5 only?
-Is RE the last step- or can you paint over it (I am assuming you cannot)?
-And lastly, what type of PPE do you recommend for this work?
