'91 Porsche 944 S2 8/22/17 Fotki update

The paint pretty much came very rough as can be seen in the photo.

Number one, the paint was old ... I used it to touch up the 1:1 around 1993.

Number two, I think the lacquer thinner evaporates before the paint hits the body. Can't find anything that says it's slower. A few spots that I got close and wetter were smoother and shiny. I never got more than 3" away with the air brush. It was all thinned to milk consistency.

I'm going to sand and smooth it out and take a trip for new paint an hour away at the Porsche dealer.

Here's a shot close to the hood latch pieces I made ..

 

I'd be happy to hear any thoughts about this as I hate painting, even though I'm not ignorant about painting and have gotten good ones.

Man Mike, that really stinks. I have been in this same boat before..

1. You can wetsand and level it out (big PITA and time consuming) then reshoot it

2. You can do touch-up on the areas that are hit light and cover them, then shoot a clear over the whole thing and level the clear (which most likely wont have the rough surface to deal with.)

3. Or the dreaded strip and start over

I have had good results with the "Clear over" method before.......just wait till the red is done gassing out.

Hope this helps......it is hard when this type of thing happens though!

I feel bad for you, after seeing all the work you did to get to this point. I have no advice to add to what Ken's already said...other than this is a very good example why it's a good habit to get into to TEST any unfamiliar or potentially 'old' paint on something OTHER than the model you want to look spectacular. The little time extra it takes to test saves huge time correcting problems like this.

Thanks for the comments, guys. I'm going to do as Ken advises and sand it out and clear it. I'm going to get some new paint in the meantime and will probably try a coat of that.

Do you think the fact the paint was old could have been the main problem here? Both bodies are rough as seen near the mirrors.

In my experience, paints that don't require a catalyst don't usually get 'old' sitting on the bench if they're sealed tight and thoroughly mixed before use.

From what you've said, it seems like your thinning consistency was right, and the distance you were spraying from was right. The only thing I've experienced that was similar to this, is when I used a thinner / reducer that wasn't entirely compatible with the paint, and it didn't really mix correctly to allow it to flow-out once it hit the surface.

I do have some new paint but haven't put it on yet.

This post was just to move everything to Fotki.

One of my favourite cars.....carry on building, I am following along

Rough does seem to indicate paint drying in the air before hitting the subject...but lots of factors in spraying to make something go weird
