How to correct a paint run ?

[AlTn]

Got a paint run while painting a cowling for a 25 hp. Evinrude. I'm using Rustoleumn Pro Grade white enamel. How long should I let the paint dry...days?....Sand it down with what grit...I'm assuming sand it wet?...Do I then need to apply more paint, or is that solely dependent on how the surface looks after sanding? Appreciate any feedback.

Rustoleum Rattle can paint can take up to a week or two to fully cure. A heat lamp might help speed it up but don't get it to close. I'd wait at least a week. Wet sand starting with 1000 grit, then 1200, then finish with 1500 Put a couple of drops of dishwashing liquid in the wather to help "Lube" the water.

The runs can be corrected immediately if you are willing to invest in a nib file. A nib file does not require waiting for the paint to cure. http://autobodystore.net/Merchant2/merchant.mvc?Screen=PROD&Product_Code=S35260&Category_Code=PSH It is an autobody item and not sold via iboats. Might even be available locally.

If you resort to wet sanding it would be advisable to do block sanding.

Keep this in mind....... we are talking about an engine cowling so it is not as large as a car.

Now here is a good tip....... Once you have your paint (ie rustoleum) on the cowling and sanded to perfection ......... take the cowling and a 6 pack of beer to an automobile collision center. Ask if they would shoot it with clear when they are doing a car. Most places paint at least 2x or more a week and nothing beats automotive clear.

Re: How to correct a paint run ?

A single edge razor blade held perpendicular to the surface can be used to scrape down the run until it is just about out(to reduce sanding), and then sanded the rest of the way out. Same technique as the fancy file gizmo. The surface can then be buffed and waxed to restore the shine. Remember you are sanding out the run so don't sand out the surrounding area paint to nothing. Where are you? I paint cars - bring it by and I will shoot it for you.
