roger1 So, it's raining hard! And, it's supposed to continue through tomorrow.

I did beat the rain though and got my top cleared. I put on 3 wet coats. I had some trouble with bugs. I think they came in through the fans which I had left in the window overnight. So, they were in the room already when I started. I had to pick a couple of them out of the top with a needle.

Overspray was not a problem with the clear at all. The whole top looks nice and glossy.

There are some dust nibs but not too bad. A couple of piece of dust are black specs. I don't know where they came from. Got to get your eye pretty close to see them. You would never see them on dark or medium color or a metallic. White (or Ivory in this case) is not very forgiving of dust with color.

The clear did lay down pretty darn smooth with almost no orange peel. I think I will just hit the dust nibs with sandpaper only and lightly run the polisher over it.

So, in summary, my makeshift spray booth is not as clean as a pro one for sure. Not sure how I really could have done it better except to have not left a way for bugs to get in the room before I started spraying. If anyone has any suggestions, I'm all ears.

Overall, I'm pretty satisfied with how it turned out. This top by far will be the hardest part of the car to spray for me.

Centerline 90 degrees? Dang! It just quit snowing here. Earliest snow I've seen since we moved to Arizona.

Lizer I'm just glad to see someone in Texas is expecting a big rainstorm.

I'll be interested to know how the clear goes on the roof with regards to overspray drying on the other half.

I suppose in commercial paint booths with the air draft coming down it probably isn't an issue.

Update

I got my last coat of base on and it did go on smoother with the slow reducer. However, I find it impossible to spray a top this big without getting some dry overspray on the 1st side I spray when coating the second side. On the first side, I start at the edge and spray to the middle and then walk over to the other side and start at the middle and spray to the edge. But, still get dry overspray on the 1st side. I hope the clear doesn't do this.

Anyway, I'll tack it off in the morning and spray my clear. I think I've seen about 3 or 4 dust nibs I'll hit very lightly with 800 before hand.

To the point of this thread, it seems my makeshift paint booth is working pretty well. I'll know more after the clear. There's a big rainstorm coming in tomorrow, I hope to beat it since I wont be able to paint in the rain with my booth setup. I'll report again after spraying the clear with a pic or 2.

Btw, I don't think I could paint with it any hotter than this (90 degrees & 45% humidity). I put the inlet of my Hobby Air unit right in front of my A/C unit in the adjacent room. The little bit cooler air going into the hood made it so my face didn't sweat. But I was very sweaty in the Tyvek suit (with nothing on underneath).

Thanks.

It was over 90 yesterday and I should have been using the slow reducer instead of the normal that I used.
Yeah, I could probably get away with sanding this solid base and then going to clear but, I think I'll be better off doing one more coat of base with the slow reducer. So, I'm going to get that on today (It's 90 again).

However, I don't have any slow activator for my clear so I'm going to get up early in the morning when it is cooler to spray that.

I'm intending not to cut and buff. So, I'm planning on 2 maybe 3 coats. However, if it looks like it's not as smooth as I want, I can always put on a couple more coats and go ahead and cut/buff. This is the largest panel I've ever done with bc/cc so it's a challenge. Here's the dash on this car that I didn't cut or buff. It's as-sprayed with my Iwata LPH-400:





I'll post back to report.

I'm not done yet but I thought I'd post a some pics.

Here's my 14' X 24' paint room before any work had ever been done in there:



Here's a shot of my radiator fan setup. I used 3 fans that gives me about 3,000 cfm of air movement. The power supply will handle 30 Amps at 100% which is pretty close to the draw of the 3 fans.



Here's a couple of shots of my filters mounted in the window holes of the garage door:





I've sprayed the white epoxy sealer and then 2 coats of India Ivory base and here's pictures afterwards in order:





I am going to sand the base, put on one more coat and then clear coat it. The base didn't go on as smooth as I wanted. I think it was because it was over 90 degrees and I used normal reducer and I should have used slow. I do have some slow that I'll use for the last coat.

I'm painting my '55 Chevy Bel Air hardtop. I'm going to start out by just painting the top and I think I'll be ready to do that Wednesday.

Just a few dust nibs wont bother me but hair would. I'll be using a hood w/ supplied air and a full suit.

I'm using 12" dual electric radiator cooling fan set for exhaust. I got a 12V 30 amp power supply off of ebay to run them. The fan set are 2000 cfm which I believe is pretty good. I thought this was a good alternative to expensive sealed fans and I had the fans just lying around anyway.

I may post a picture tomorrow of my setup and see if you guys might have any suggestions.

Centerline Don't let anyone fool you about a home booth. You will have to cut and buff the final product. No matter what you do you'll get some dust nibs and the occasional hair in the paint. Don't let that worry you though. Its all part of the painting process.

39chevy Finally got it really good, thanks again, Hey if mine comes out half as good as yours I'd be happy, and thanks again, Dana

Centerline If you're not going to put plastic on the walls you could run a cross flow booth where you have just as much air coming in as going out. But if you're going to use plastic to cover the walls (I suggest you do if you don't want them painted too) then just keep more coming in than going out. You could use one fan sucking air out at your walk in door with the other two at the garage door pushing in. That will work. Make sure you use decent filters and let the fans run for an hour or two before you clean the inside of the booth. This will let any loose filter material to be removed before you paint. After you let the fans run a while, clean the inside of the booth the best you can to get any dust out before you bring the car in to paint.

Good luck with your paint job.

39chevy Centerline, Very nice paint jobs!! O.K. I hope I don't sound like a broken record, But This is how I was going to do my (1) car garage booth, I only have rigid walls and now I will put 2 box (20 in) fans underneath garage dr, enclose the rest of the garage dr top and bottom. Then my side dr (walkin) at the opposite end, but still on the side wall, should I put only (1) filter to exhaust? I will enclose the rest of the side dr, I just want to make it clear, thanks again, Dana
