What should I sand with?

[dullbird]

Hey guys just a quicky

I'm going to move the firewall and the cab back etc in to the garage tomorrow so I can start doing a little bit of work on them.

can someone tell me what sand paper I should be using to rub these pieces down with before a primer gets thrown on

is it worth using an orbital sander? or better just to lightly sand by hand

thanks

I used 100 grit open cut paper [ thats the white sheet paper ] to do mine and I used just a normal sander, doing it by hand would take too long , and too much pain especially to feather edges, you can see mine came up alright.

I think I only got an orbital sander will that do the job?

also if I was looking to put some bog on the doors would the 100grit be good enough for this or should I be looking at a more 60/70 paper

Thats fine, it'll do the job not a problem !

I had no choice with mine, but to use an angle grinder with a wire brush to take it back to bear metal. There was just to much rust/ surface rust.

But if yours is pretty good id go with what Tonestar has suggested and use the 100 grit on a orbital sander.

I dont need to take back to metal just rough up the surface for a primer to stick to really

400 to 600 wet & dry if you just need to key it up to spray over it.
Unless you go back to bare metal, you won't need primer.

Key it in enough to take out the original orange peel and oxidised paint and even it up. Wash it down with either Prepsol if it's got oil or grease on it.

Factory paint can be quite thin if they're ally panels and if you expose any metal your going to need an etch primer to cover it, resand and then paint it.

Peeled paint, sand and feather all edges, etch, build then sand to finish.

a few people said I wont need a primer how ever my only concern on not using a primer is I have some many different coloured panels and some of them are quite dark I was concerned that I would have to use a large amount of paint to cover it up.

Is this not going to be the case?

Can I ask what you mean when you say feather edges? this is the second time I have heard this phrase

Don't try to apply too much at once or it's going to run. If you have existing dark colours and colour being applied is lighter, add a thin base coat first let it dry totally then sand off any gloss and then respray as usual.

Feathering is basically sanding the edges into a smooth transition. Stops lumps and lines appearing under paintwork.
Please don't tell me your doing it with a spray can
