Single Stage Urethane Touch-up

[EngineerDoug]

Hello all,

Thanks to all of you who gave me tips on laying out the paint on my '68 shell. I painted it this weekend, and I think it turned out pretty good under the conditions I had. It was cramped, I needed more lighting down low, and sweated way too much in the respirator + bunny suit.

After it was done I did find a couple of areas that require some attention. I missed full coverage on one of the wheel lips, for example. So once the paint fully cures (I assume in 7 days or so?), I will need to apply another coat to these areas. Any advice on how to do this? Sand/scuff? What grit, etc?

I am fully prepared to cut and buff after that, but would like to be sure I get the touch-up done right first. The paint is a single stage urethane in sublime:

Thanks in advance!

Doug

I've blended clear before and that takes some skill, but never blended single stage. I'm sure there's a way it can be done, but it's going to be some challenge to it I'm sure. If you could find a body line to bury the blend in, it would be better. I would scuff it with 400 before shooting over it.

Welcome to my world of painting.
Last I did was in August 2017 and I barely made it to the cold shower.
I'm no professional but I've done plenty of touch up because I drive my cars.
As said, go to a body ljne with the touch up paint.
Hide it there.
I've never had any luck "blending" mid panel and all my work is single stage.
(No clearcoat).
I would suggest only very fine wet sanding prior to the next coat.
Maybe 600 or 800 at least.
With fresh paint I don't even think that is necessary but will make your next coat better.

Maybe one of the resident experts can help... @eldubb440

OK here is a shot of the worst spot. This was a maneuverability problem - I just did not have enough light and did not turn the gun enough to get the entire wheel well lip.

I also have an area at the top of the quarter panel that you really can't see in a photo, but the coverage is too light. It looks like just one coat over the sealer. That one will be more difficult to blend because there are no nearby style lines to pick up.

Thanks.
