Water Streaks In Paint?

[TheCamaroKid]

Last week I finished a 1969 Camaro SS body. I cleared with Tamiya lacquer. I let the paint set for a week. Today, I went to do the windshields and bumpers. I saw a video online of a guy gluing windshields and bumpers, he used a damp paper towel to wipe any excess. I did the same but I got water streaks on the rear quarter panel. I tried wetting the roof of the car with water and wiping it with a microfiber cloth and also got water streaks. Is there any fix for this? Or did water just ruin a perfect paint job...

What kind of glue did you use?

I’m guessing that the water marks are actually dried, diluted glue. If it is a PVA type glue, you might be able to remove it with a wet cloth, rubbing it gently. If not, PVA glue shouldn’t attack the lacquer, so should be able to buff/polish it off with some polishing compound.

It's that Florida well water.

It's the Tamiya Clear Parts Glue. What type of polshing compound should I use? Would the Tamiya Finish work?

Try hot water first, on a clean cloth

I tried both. Sadly no improvement.

Would just rubbing Meguir's PlastX on the car with a cloth fix this? I can pick up some tomorrow.

My guess is that this has little to do with water streaks, and is more likely diluted glue smeared on the surface  as Bainford said.

Any fine abrasive polishing compound should restore the finish.

If it were mine, I would give it a quick once over with Novus 2 “Fine Scratch Remover”, but that’s just what I happen to have on hand.

Any fine polishing compound should work.

Ok. What's the best process? Wet sand with a really fine grit sand paper, then rub in the compound?

Probably no need to sand if it’s just residue.

The polish should be all that’s needed.

just apply it as you you would polish to your car.

If one application doesn’t do it, hit it a second time with a little more muscle.

Awesome, I'll pick up a bottle of PlastX on my lunch break and give it a try. Fingers crossed.

Good News everyone. I tried the PlastX. I got 90% of the glue and streaks off. The roof looks really good. It did leave a slight polish cloud. I will likely try again later to really buff it out.

If you happen to have any automotive polish sitting in your garage, try some of that.

I use Turtle Wax “Scratch and Swirl Romover” as my finishing step when polishing bodies. 
 

It gives me a very brilliant, reflective finish.
