Hi Bruce
If you didn't put on the clear coat, its probably best to wait the 5 days. I use enamel and wait almost an hour between coats, then very lightly buff with 400 grit or finer just to smooth it out, then wipe with tack cloth. 3 coats is usually fine . 2 coat of clear coat have not seemed to require sanding between. I just sand, wipe, spray, hang up and set the timer to go to something else for an hour.
If you can't bake it, its been advised to let the scope parts cure for a month or so before assembly and mounting. I have a little 50mm with mooshed paint under the mount brackets to attest to that.
