Hi guys,

I started jamming and painting the underside of the trunklid etc. I'm running into some dust getting into the paint. I don't have the best place to paint, but its fairly clean. Can i just wet sand/buff the clear to remove the dust issues?
Also can I reduce the clear some? If so with what? Im using omni mc270 with a medium speed hardener MH277.

Here is a picture of the underside of the trunk lid, the picture doesn't do the color / shine justice. The blue is really much deeper. Its only the first coat of clear also.

BTW I know i said thank you for all the help and and an awesome forum , but thanks again. I didn't think I would be able to paint my car , but with the information/help on gun setup, painting, trouble shooting etc..etc...on this forum I feel confident enough to do it! So thanks again!

Bob

Yes you can wetsand and buff the clear to remove dust, and yes your bound to get some dirt specs in the paint, even in a booth.
You could buff the inside of the trunk lid, provided you put on enough clear, and be carefull around edges, but I wouldn't want to buff the inside of a trunk lid with all the knooks and crannys and edges.

Since you can remove the trunk lid, and looks like you already have, You should be hanging it and painting it verticle. Normally you want to paint your base if a metallic color in the position it sits on the car, and then can clear hanging, but don't see the inside of the trunk lid being too critical of position. Hanging will cut down the amount of dust that can land in the wet clear, and you will probably come out with a much cleaner job, just be a bit carefull as it will be easier to get runs if you go to heavy, or too cold.

I don't see why you can't reduce the omni clear, with a good line of reducer, such as ppg's dt series reducer if you wanted. But it could be easier to run if you reduce, and you will need to allow good flash times between coat. Its been ages since I used omni clear, but seem to remember it laying out pretty well for me without reduction. If you do reduce, I'd try to stay under 15 percent.

Thanks guys , I did happen to run into the PPG rep on Friday. He recomended adding just a small bit of reducer to the clear also. Worked great!

Yes you are correct, I really dont want to sand/buff the nooks and crannies on the inside of the trunk.

Here are better pictures of the trunk , it represents the blue much better and closer to the blue than 1st picture.

But I have another question, just for "practice" I wet sanded the trunk with 1500,2000 grit wet sand paper then used the red rubbing compound, followed by the white polishing compound, then used a 3M scratch / polishing compound. As you can see there are still minute scratches in the finish that show up rather well. How do I ged rid of the fine scratches?

The paint guys said it sounds like scratches from the wet sanding step, and i need to rub it out more?

Any suggestions?

Bob
