  View original topic: Blocking Primer On Panels with Lows

Hey folks,
I'm doing all the bodywork and filler work on my 73 Beetle and I know I have a few lows that my skills/patience didn't quite get out before I found someone to help me get the thing in primer. I don't have the equipment (or temperatures nowadays) to shoot new primer so I need to sand what I have down so it's ready for Maaco to shoot color on it.

I'm not going for a trailer queen, show winning car. I don't have the skills or money. I'm going for a 10-20 foot beauty and some waves are allowed. It's a 40 year old car after all!

So with that in mind, I know people recommend guide coat but that will obviously show if I don't get it all off when I'm blocking, right? Do I guidecoat anyway and take my high areas until the primer starts looking thin and then sand the guide coat out of the lows by hand? I know it's not the ideal method but again, I'm not going for perfection, just a rust free "pretty good."

And, because I'm proud of the thing, here are some pictures even though they don't give too much idea on how smooth it'll be.

The whole purpose of the guide coat is to highlight your hi and lo spots while sanding. This allows you to easily spot where you need more work.

Unless you're going to address the highs & lows, why guide?
