Do any of you old time painters remember a product called liquid guide coat? It was just as it described, a light black liquid guide coat that you wiped on and it dried almost immediately, worked fantastic for getting into sand scratches and pinholes, and wont wash out when wetsanding. Unfortunately, I have not been able to find anything like this for a long time, only spray bombs and wipe ons.
Anyone know if a product like this can still be purchased?

I remember it and now they have a powder type that you rub in with a rag and it works way better than spray can for finding pin holes
Spray can is good but not for finding pin holes.

I agree, the powder wipe on is better than the spray on, but is still susceptible to washing off when wetsanding. But I fear its the only viable option nowadays.

I'm not sure what you're doing but I always do this on the last coat of primer. 320 grit dry sand with a soft block and that should find all the needed areas to be fixed. then sand it again with 500 grit dry paper or you can wet sand with 600 if you want.
I'm not the smartest guy around but been doing body work and paint for over 50 years and unfortunately still doing it.
I'm sure someone will chime in and prove me wrong as always but just my 2 cents.
Don't mind helping you if you need it.
 
I just finished the bodywork on my Dart. I used the dry powder (Norton). I used it up to 320 but not for 400 or 600. I think that process is common practice?

I used to be a professional painter in a shop for years, got out of it a while back due to health reasons, but I do appreciate the offer to help! I typically like to use it after blocking with coarser grits to make sure I get all the sandscratches out, and sometimes on my final wetsanding just to make sure I got everything.
As much as working on the floor used to drive me nuts(shop owners mostly), I do miss it when something needs to be painted :)

Same here and my Scamp was the last thing I painted back in 2019 and I got sick so haven't painted since.
If you ever get down to North Dakota please stop in I'd enjoy a visit with ya.
Pictures of your car would be nice to see.

That would be nice, Id enjoy that too, and vice versa about coming north to Saskatchewan :)
Heres a fave pic of mine, this was taken as I was waiting for the flatdeck to take her off for new exhaust, hence no exhaust tips
How about you now? :)

Love the 340 and been my favorite engine.
Mine is a Blue Print 408. I am no engine guy and just decided to pay to get it done turn key.
I wish I could have done my whole build myself but I am stupid when it comes to making horse power.

Nice! Mine was done when I bought her, so Im not quite sure whats all inside. Im no newbie when it comes to mechanics, but I have nowhere near the skill of some of the guys on here, Id rather paint!!
That is a beautiful car you have man :thumbsup:
 
Since I am fairly new to bodywork, I never knew you could buy a powdered guide coat you wiped on with a rag.

However, I found out really quick in my adventures that using flat black primer for the job was not something you want to do.

So, I ended up using SEM Guide Coat Black and I really like it. It covers really well and dries in seconds.

I'll have to pay attention to it the next time I use it and see if it's filling any pin holes.
