    Hey everybody…

    Well, got color and clear on the majority of my car today, and I am pretty satisfied. The basecoat went on beautifully! No runs, no texture issues, just a few pieces of trash I had to sand out and recoat.

    But when I got to the clear, It looks ok, but I had a couple of big runs. I think I rushed it because the guy at the paint store told me not to wait more than 10 minutes because the paint begins to cross link? and would crinkle. SO I rushed it a bit. I think if I had been using fast hardner, I probably would’ve been ok. There are places where the clear looks like glass, and a couple places of serious peel or texture issues.

    My question is, can I recoat the clear after it has cured?? The tech sheet (PPG Shopline JC620 urethane clear) says after 8 hours at 70 degrees, so I assume I can, but do I need to do anything differently?? Thanks guys.

    youll need to flatten your clear with maybe 500 grit before u reclear. 10 mins between clear coats is fine for that clear but fast hardner on a complete is a big no no. next time, keep your hand moving and use consistent even passes and youll have no runs

    i cannot see your photos, but if it was me i would block out the runs with 400 wet and flatten out the peel with 600 than etch the rest of the panel, mask off what didnt need attention and re-shoot the clear. i wouldnt take the chance of having adhesion problems. its better to be safe than sorry in this case

    let the clear get nice and hard so the runs sand out easier. the runs will stay softer longer due to the extra material. you can hit them with some 600 to open them up and let the solvents escape easier. once they are cured block them out with some 400/600 grit and a hard block. dont be surprised if you break through the clear (especially since this is your first time). once the runs are blocked out, prep the rest of the panels and respray

    I would shave down your runs with a nib file or a single edge razor using it like a wood plane to shave the majority of the run off.Then go to your sand paper and a small block to finish leveling it(I use a hockey puck cut into different sizes) and get ready for paint.Don’t sand across the run you want to sand with the length of the run to knock it down.
