I recently saw a thread about spraying plastic kote spray or coating on a fuse box before installing to keep it from corroding , I am replacing my swiss cheese fuse box < accurate description due to the many fuse holes > with a very clean one from ebay , the short tail style , was hoping if someone knew the exact name and how much to spray on it , I am hoping to avoid redoing this job again, also any suggestions in area of contact cleaner , i have to clean all my contact I am sure I don't want a repeat with this box, thanks

There is nothing you can spray on plastic to keep it from corroding due to extreme high heat.

I think seerex is asking what type of spray coatings are available for the metal contacts so that they do not corrode and get hot in the first place.

I have seen small spray cans of a plastic/rubberized coating (which is what you are talking about I assume) that are intended for spraying onto battery terminals(with cables attached, to seal it off). This might work for the back of the fuse box, where things don't need to move. I can't see it working for the business side of it though, since you would break the coating every time you needed to swap a fuse.

I think I may have a can of it out in the garage, I will go look and see if I can find it later.

To keep the front of the fuse box clean, there's probably something you could buy at an electronics store that wont break the connection yet sit on the surface of the fuse clips, but I don't really have much experience with this...

Why couldn't regular Di electric Grease (probably spelled wrong) work for this?

AFAIK, nothing is going to protect the plastic from deterioration (it's not really corrosion as stated previously) caused by heat.

Instead of spraying, I'd suggest you consider using a small brush to paint on a coating.

Also, in R/C boat racing, we use a dielectric epoxy to encapsulate the electronics, protecting it from water.

I picked up a jar of liquid black electrical tape years ago for my boat to waterproof some connections. This stuff worked just fine, you apply it with the brush that's attached to the cap of the jar.

I picked up a zinc spray that supposed to keep the contacts on the back from corroding, I haven't used it yet , I was also considering the liquid electrical tape , anyone every used spray on zinc?

Will zinc conduct electricity? If it will, you will need to be sure that no circuits are bridged by the spray application. I would consider using a brush on type of application to ensure there are no bridges. Spray into a cup , then brush it on from the cup. But of course, I'm anal about stuff like that.

put dielectic(sp?) grease between the contacts and fuses then it will keep good contact and not burn your fuse box they tell you to use it on spark plugs to so you dont fuse the clip to the spark plug

Dielectric grease sounds like an oxymoron. You put it on electrical connections, to protect it.
