How to dull jams

[Kenneth B.]

What is the best way to dull jams that had been buffed before to pass NCRS? I hate to lose all the paint points but bo not want to have to repaint jams. The Corvette was restored 30 years ago long before the NCRS deducted for it. THANKS

I've used White Rain hair spray. Car has been judged twice, NCRS Regionals, and passed. Not permenant and can be removed.

Clear MATT in a buzz bomb works great.

Re: How to dull jams

Ken, there was quite a discussion on this some time back (maybe over a year ago). It's in the archives and even talks about using Scotchbrite pads and steel wool, although it does'nt talk about the orange peel with those methods.

I don't know what a "buzz bomb" is, but you can use gloss clear with a flattener (I think about 20%??) in a rechargeable aerosol can from Harbor Freight. There was also a discussion just this week about a company that can put whatever you want in a can (the thread had to do with redoing the underside of a hood).

Michael's suggestion was also discussed in that older thread and I may buy some hair spray just to see what it looks like, since it can be washed off.

Ken,

I had success using a clear primer from Duplicolor. It provides a matte finish. It's advertised as a primer for use under flexible bumper coatings but appeared to work fine for this purpose. Use a very thin, almost dust coat and don't let it build up. I'm sure other clear matte finishes are available, but the reason I prefer Duplicolor is that for the last several years I've had constant problems with paint spatter from typical rattle cans. Duplicolor (and also Krylon) have a unique style fan type spray nozzle that creates a perfect spray with no spatter.

With my first judging, my original glossy jams resulted in the maximum deduction. The second judging after dulling the jams rectified it.

Use a course poslish compound and do not proceed to finer polish. Remember a clear application is a deduction for any judge that knows anything about paint. But most don't.

Agreed, my experience too. AquaNet Extra Hold also works well.

Re: How to dull jams

You may have some success with these methods but don't count on it. The judging standard says nothing about dull door jambs, what it requires is a correct factory appearance. An original appearance on door jambs involves a lot more than gloss level. Door jambs are judged under the interior section but the can be used with exterior judging if there is a question on correct application method, in this case expect a more critical judging with a lot more points at stake.

THANKS GUYS
I know I will lose some poins but I don't want to take a total deduct for paint & condition.It is a big hit in points. I have been down that road before.

Re: How to dull jams

If a Corvette is not painted correctly why would one expect to get away without deductions. Corvettes were never painted with base coat clear coat. It is completely wrong and not representative of a "restored correct" job. Guys need to stop expecting this be over looked just because the door jambs don't shine. Hair spray, what a joke. What ever happen that a second flight is not acceptable. Top flight is assumed automatic just by showing up. There is more and more acceptance of wrong............

Re: How to dull jams

A most prominent reg/nat exterior judge advised me to dull the jams, drip rails etc to avoid a total paint deduction....I don't think anyone expects a top flight just by showing up but for those with a bc/cc paint job the advice given on the judging field is in lieu of a total repaint dulling certain areas will mitigate point deductions. Just like with any restored part paint is judged on how closely it appears compared to the original with appropriate point deductions for deviations.

Re: How to dull jams

The term "dull" the door jambs is misleading. The jambs, hood ledge, inside the vents, cowl vent panels and any unbuffed areas should appear as unbuffed factory lacquer. Keep in mind that at the factory these areas normally got less coverage but were still subject to the reflow ovens. The door jambs got little or no primer or sealer and only one color coat. The purpose of the reflow bake cycle was to let the finish flatten out or lay flatter. The jambs etc. still exhibit some degree of gloss just not bright and shinny or block sanded and perfect. The standard deduct for paint allows for a finish other than factory applied if the application method appears correct, that is to say if the jambs lower areas etc. appear as you would expect from the factory process. The deduct for obvious clear coat or other type finishes is 100%. If the application method appears correct 50% is added back. With only a 50% deduct you can the get the appropriate condition points. With a 100% deduct you qualify for no condition points. You must have at least 90% originality to get any condition points. This makes a huge difference in points awarded. I would says this makes it worth a little bit of extra effort to achieve a correct appearance. There is no something for nothing if you want paint to achieve the highest possible score.

Re: How to dull jams

I agree with Tom, that the jams were just unbuffed, no matter how the paint came out of the gun. However, my experience is that the jams and hood ledge on C-2's are much duller than C-3's. The C-3's with the exception of the 1968 model year (because that is a weird production year) is not as dull or flat as one might think. QC was improved on the 69 thru 72 models and the jams and hood ledge do possess some what of a shiny finish. Of course not like the top of the car.

SIR
I am not trying to get 100% paint points but I also don't want to lose all the paint points just because 30 years ago for you info with laquer paint & the jams ETC. were buffed. I don't beleave in the 100% deduct but it's NCRS'S ball & I am trying to play the best I can with out having to repaint the whole car. I would be happy with a second flight or even a third flight. Do you beleave that repo tires should get full duct for not having DOT also along with any other part that is not 100 % correct?

Ken, I thought that if your car is painted with lacquer but buffed out to much, would that not just be over restored? as the new judging card for paint states- does the car appear to be like the factory applied material. over restored is a 20 percent deduct.

The repro tires where recently touched upon, If the tires are correct then its just a 3 or 4 point deduct for DOT stampings. Now you need post your repro tire type. Maybe one of the experienced judges Like Gene could touch upon.
