I remember using CD2 when I was in high school (won't say what year the cars were back then). I was disappointed when it poofed from the store shelves but recently acquired a stash.
BEFORE
You need to start with a clean engine bay. Put newspapers under the compartment because you need to saturate the parts and there is always some drippage!
It is super wet when first applied but the solvents quickly evaporate away.
DURING
You walk away for 20-30 minutes and then start the car to "set" the finish. Afterwards you can drive for 20 minutes to finalize the look !!
AFTER
The white spots on the final pic is just dust after the car set for a spell. Pay special attention to the look of the bridge and hoses!!
Must stress that the engine bay needs to be clean ahead of time, this is not a cleaner but a final spray product. Put something down to catch the drips and ENJOY
