Hi

I have just finished painting my mini in cellulose. I have applied 4 coats, and in one area there is a paint run. With cellulose paint, what is the best way to remove this?

After leabving it for at least a week to harden, I was thinking of sanding it out with 600 Wet & dry paper, then using G3 cutting compount, then finally polishing. Does this sound correct?

Thanks

Sounds like a good plan, but I would go about 1200 wet and dry soaked in a bucket of water.

It may even work just using the G3, depends how bad the run is. Be careful though not to rub too hard and try to resist using the tips of your fingers. Try to use the section of your hand between the base of your little finger and wrist to apply a more even pressure. Grip the wet and dry between your fingers to stop it slipping...

Does that make sense?

I had a run on Ratty, I was able to use a stanley blade and cut most of the run off then flat
and cut back..

Although this may seem odd to some, its a professional solution, I have a selection of specific file blades for this. Let me know if you'd like to borrow one John.

Hi Paul
Thanks very much for that, really appreciate it. I have no idea how that would work, but obviously it does! You are welcome to pop over some time and take a look, as you also live in Milton keynes I see.
Cheers

PM an address and phone number and Ill pop over one evening to see what would be the best solution.

Cellulose is good for one of these reasons, when you get a run you can flat it out with some wet and dry (I use 1500 to be safe), bit of polish/compound and the runs disappears.

With a magic marker, mark a line under the run. Sand until you are just sanding the magic marker off. Then go through various grades of paper upto 1500 over the whole area and then G3. Youve done well to only get 1 run. I'm doing mine at the moment and get many more luckily with celly you can do the above (without the G3) and wack another coat on the panel or on the area of the run.

depending how big the run is I use a run razor...it's a razor that can be adjusted with a guide ether side. Then as said above 1500 wet & dry and polish off

Hi
Well, there is a very slight orange peel on many of the surfaces which i am sure i can easli remove. You mentioned i did well to get only one run. Well, the spraygun is a devilbiss GTI pro which is HVLP. Its so easy to use and getting runs genarally occurs with a split second lapse of concentration. But i think its less likely to cause runs than using the cheaper guns.

I will leave the paint for several weeks to get really hard before i think of removing the run and polishing it up etc.

Like the man said. 1200 with lots of soap and water and a cork sanding block if you can find one, you don't need anything coarser and it doesn't leave deepen enough marks that tee cut won't easily remove. Go carefully as it cuts much quicker than you think. When it's flat, just Tee cut it with good soft mutton cloth, not the cheap coarse stuff.
