need info on over spray on floor

[59mgaguy]

first things first I'm a 78 first timer painting. I must have the record for calling SPI. I just got done spraying the epoxy sealer coat and I do have a few nip and faults. But not bad for a first time. I've tried sanding the nips and I believe they turnd out OK but I do have a couple of spots that look like the hide of a gator.. Sanding with 1500 doesn't seem to cut it. My question is do I need to spot spray with my epoxy sealer over those spots, leave as is, or ? Also before going to my base coat I have over spray on the floor. I figure when spraying this will kick up and get in my base coat. How to clean the mess up on the floor. My body is locked in the spray booth I made. If I tear out the front and move the body out side I'm afraid it will have more dust and crap get onit. ( I sanded the 2K out side and it became a target for the birds) And how much dirt will I get back on the tarp cleaning.

Any idea on what to do. (just forget the dust and spray base???? Dust can be seen in picture booth and car

Based on the two close up pics, you're definitely not ready to spray base. Sanding dust can be handled with a shop vac with a good filter. Once I'm anywhere near ready to paint, I avoid blowing dust with an air gun. Some of the pros will hopefully add to this, but I'm thinking you'll need to re-seal the entire body rather than spotting with sealer. One purpose of sealing is to provide a slick uniform surface for base, and its doubtful you'll get that by spot spraying.

that epoxy is a little textured for sure. i would lightly sand the texture out with 600 grit then if its been more than 24-48 hours since you shot the epoxy you will need to shoot another sealer coat. this time you need to reduce the epoxy way more. mix it 1:1:1 then shoot a super thin coat. it does not need to cover. just a micro thin coat. its just there for adhesion. after that go right to base. i would not worry about overspray on the floor. you can wet/dry vacuum it up but generally dust on the floor is heavy and is not what gets in your paint job.

I think a lot of what gets on the paint job comes off of you.

Also the car. Under fender wells, etc.
