Since I'm pretty new to all this car stuff, I got my father in law to show me a few weeks back how to strip the paint off the mini's roof, then beat out the dents and the fill them. we did the entire roof over the day, but only got around to sanding back 1 half and everything seemed fine.

today I went to sand back the half of the roof that we didn't finish... and when i sand, within about 10 or 20 seconds, my sandpaper is clogged up with filler....

Is that normal? i didn't seem to happen when we sanded the other side of the roof on the day.. but maybe I'm just remembering incorrectly?

Can you push your finger nail into it? It sounds like there is not enough hardner or was not neaded though completely?

Just went out and "tested" ... i cant seem to damage it at all if i poke it or scratch at it with my finger so it seems pretty hard.

maybe its just the cold weather making the particles stick together on the sand paper or something like that?

is it kept inside or outside?

It may have soaked up some moisture.

what sort of sandpaper are you using? cheap stuff will clog. but if using the same stuff as previously then i cant be sure, could be a few things like moisture getting in or there could be a timeframe that you the filler recommends to sand

It will clog quick(ish).

What grit are you using?

Start with 80 then smooth it with 120 then 240. It you are using too finer paper it will clog quicker. Get the shape with the 80 and fisish with 120 and 240.

You should get about 15min of continueous sanding out of 80 grit.

DO NOT BE TEMPTED TO WET SAND IT. Yes it will stop it clogging but the water will soak straight thru the bog and rust the panel out form under the bog.

Another thing to try is a Wrasp (rasp). You can get cheap ones from bunning for about $20 or something. Its like a file, but it won't load up. Get your shap with this then finish with 120 and 240.

<EDIT> Trying to load photo opf wrasp to photobucket... be back in a sec

Here's a wrasp (rasp... however you bloody spell it )

Its a good substitute for a body file and considerably cheaper.

PK, how about freecut paper (the white stuff) is that better for sanding bog than normal wet & dry paper?

personally I use free cut.
using a random orbitol sander smashes it heaps quick as well!
Isnt a wrasp/rasp file also called a cheese file, or is that something different?

mooo, I'm a pig!

Fre Cut (yep correct spelling) is great because you can sand as quickly as you can wet but with out the slop, so you save time on the clean up.

Also as soon as it does get loaded you can just bang it and all the dust falls out.

If you can't get the 3M Fre Cut don't bother (well at least this was the cas 3 years ago that may have changed).

With carbide paper, the grit both blunts and falls out much quicker... and it loads up quicker when used dry.

For sanding bog, fre cut is great.... thanks for the reminder

(again use 80, then 120, then 240)

Nope same thing, cheese file, wrasp/rasp whatever you want to call it... Surform I think they are called too sometimes...
