What to use on panels as a secondary visual guide?

Last week I washed the car to clean sanding dust off it. While washing I had a layer of water on the roof which allowed me to look and see if I had any lightening bolts from the reflection of my ceiling lights. The roof looked very good to me with no lightening bolts or distortion.

My question is, what can I use on the vertical panels, ie; quarter panels, doors and fenders to check them? I've seen some videos where they use prep solve to check? I'm looking for something not to expensive and won't evaporate to quickly.

Thank you,
 
Your first guide should be your hand. Your hand can feel defects on the micron level. It's the best tool a body man has. If you are having trouble feeling a panel you can use a prep towel or even a paper towel or thin cloth between your hand and the panel. Closing your eyes also helps.
As for your question solvent W&G remover works well. SPI 710 for example. But your hand should always be your first choice.
 
"closing your eyes helps". You know,like a doctor does during your prostate exam..... Wait,I think I may need a new doctor!

Oh man you just had to say prostate exam. On my very first prostate exam when I was bent over the table and my female doctor was putting her glove on, I looked over my shoulder at her and said, I don't know who's going to enjoy this more, you or me?

That is when I found out my female doctor didn't have a sense of humor.

Anyway, back to the thread topic. I use my hands, I use guide coat and a long block. Obviously it worked because the epoxied roof looked really good wet.

I'll use 710 to check the vertical panels as a 2nd visual guide after blocking with guide coat and after spraying epoxy.
 
When I worked at an auto stamping/assembly plant the inspectors had a clear, very light weight oil that they rubbed on the panel as smooth as they could and checked it with fluorescent lights. I have no idea what type oil it was but it was a lot like some cooking oils. The panels were unpainted, unprimed and would be cleaned thoroughly before a finish was applied.

We would also use a very thin glove to check for defects. Generally speaking the women could feel a smaller defect than a man and I'm guessing because they usually had smaller hands.

Like 90 also makes a product called panel check I sometimes use it in the booth to check tri-coat color matches and all the time to check panels after final blocking

Thanks for posting and speaking up. Looks like a great product. Seems a bit pricey though for a 10oz can. I sure would like to see an MSD sheet on that product. I checked out Big Kid Blocks who makes this product. Pretty cool sanding blocks.
 
How long would you estimate the 710 stayed wet, and how did you apply it, sprayer or soaked towel?

It lasts long enough to get a good look, and I used a soaked towel. The streaks from wiping it on level out after a minute or so.

Yep, without my hands I'm blind. W&G works real good also bobbing my head around and walking around using the light reflection or another stationary objects reflection as a guide.

My guess is that the women had softer hands, thereby more sensitive hands. I know some guys can't feel anything, and I wonder if maybe that has to do with how callus their hands are. There is a point though when 710 is needed.
