Maybe this one's for Roger; but I was wondering if anybody else is experiencing this?
We use a good deal of the aluminum panels with the baked enamel finish. I don't remember having this problem until fairly recently; but after wiping them down with Rapid Prep, masking tape does not want to stick (like to hold up a pattern).
Duct tape will stick; but even that doesn't have the "grab" that it usually has.
Has the formula changed on the Rapid Prep, or are the panels using a different paint system?

Dale, I always sprayed on and wiped off a couple of applications of Rapid Tac after using Prep.
Might help?

You DO need to rinse the Prep off before applying vinyl. Prep is strong enough that it will also attack adhesive. It can be rinsed with water, but Rapid Tac does a better job, because they are designed to work together.

Dale...For most purposes, I used Rapid Tac as the surface cleaner. Only ocasionaly would I use Rapid Prep (or laquer thinner or enamel reducer), to remove tar or grease. But it still required a final clean-up with Rapid Tac to get a squeeky clean surface.
Kinda the same as when I removed previous graphics, I used Rapid Remover to get rid of the old adhesive, but followed up with Rapid Tac to do a final clean-up.
There really is no "one step" solution to getting a perfect vinyl receptive surface.

I had the same problem trying to tape a pattern after cleaning with Rapid Tac. I simply took a new paper towel and more carefully wiped down the surface. Masking tape worked fine after more complete wiping.

Most aluminum panels are powder coated, not baked so they are slicker than they used to be. At the same time, powder coating has some texture which aids adhesion. The other culprit is the maskant which have had their formula changed so that they can be recycled. Because of this, more residue is left on the surface which requires a clean and lift method so that the residue is not spread around on the surface.

Thanks Kent. I have noticed that some of these panels seem to have a little different appearance than they used to; possibly due to powder coating.
I'm surprised that Roger Bailey hasn't chimed in on this. He might also have some constructive input. Or maybe, it'll involve another product....
