I noticed in the DuPont tech manual on "blending" that they recommend
adhesion promoter put down first and extended out past the final
blend area. I thought this odd, does the adhesion promoter that's
left exposed just buff away? I've never tried that.
Anyone here do it that way? :pimp:

I read the tech-sheet. Did you notice paragraph 3, page1:

*Clearcoat Blends within the panel [open solvent blending] are not covered as a DuPont Warranted Systems
repair; insufficient clearcoat film build will contribute to poor durability and poor film property performance.

That is a disclaimer telling you that if you choose to use this method your on your own. Not covered under warranty.

That’s why I suggested the other method. If you’re going to rely on the tech manuals I suggest you pay attention to the disclaimers in them.

I agree, but that's not the question.
Believe me, I know how to blend, I've been
blending for over 30 yrs.

I'm still looking for an answer to why "THEY" (DuPont) would
recommend leaving adhesion promoter uncovered.
Do you buff it away after you're done ?

(Why is that question so hard to understand) :confused:

Yeah, for sure the adpro buffs right off because it is so thin, but there there must remain an edge of it that will be exposed right by the clear. Obviously Dupont feels adhesion is the main concern, and maybe their adpro is UV stable, hard to say.

P.S. I have done a similar procedure in jambs, with Bulldog though, where an area around the latch gets fixed and spotted in. It works good in jambs...

In part 4 of application they explain to mix adhesion promoter with your mix as you read. However, the last sentence tells you to reduce further and finish off your blend. Meaning go ahead and cover that area previously uncovered. It can get confusing the way they write their instructions.

Their method is not the best in the long run as in the future it maybe buffed by someone who doesn't know about the blend. Used car dealers use that method to repair their vehicles. It looks good going down the road till later.
