As above. Ive had a full respray on my xr3i and having a few electrical problems which i think are due to bad earths.

I have to away abit of paint to get an earth but don't think there good enough.

Whats the best way to get a good earth without making a mess off the new paint job?

I beleive u dont have to sand etc as the bolt will transfer it to the shell (or so im told)

Ive had to relocate some of the earthing points so they would be just earthed to paint which isnt good enough.

I was going to mask off a little area just big enough to earth to and put a little bit of turps just to get a good clear area but then i dont want it to rust

Adam.

Maybe use a dremel to bare metal just the exact shape the connector will take up? (if you have a steady hand )

Adam.

PS i will be doing this in the next week , so will be interested to see how u get on

Had to put the engine and whole car back together when paint was only 2 days old. God knows how i didnt scratch it!

Its the base coat thats the tough one to get off

Only way is to scrape the area back to bare metal. After you connect the earth, a smear of petroleum jelly (Vaseline) all round the join will prevent rust, just like you do with battery terminals to prevent corrosion.

i re-taped the holes and used a smear of conduction grease on a new bolt.

So i can use any grease? It won't prevent a good earth?

it will make it better if anything.

If i were you id use copper slip

you could try those serrated washer type things, as you tighten the bolts they scratch the paint until they hit the metal giving you a good contact point
