I know there’s a ton of threads on Master Series, but I didn’t see any specifically for AG 111. I want to apply it on top of Master Series silver primer/sealer on my sandblasted chassis and a set of new floorpans (the pans I will probably sand instead of blast and then coat with the MS primer). If I use a foam brush, will it smooth itself out? I am concerned that with a gloss finish I may get brush strokes, etc. I know their website says “never a brush stroke” in the description for the primer, but nothing about the AG 111. Thanks.

Here is some information I got directly from Chuck P (vwspkitman). He sells and uses the MS silver and AG-111.

Start of quoted message:

If you are doing the entire inside of a Ghia , you will need more than the 2 quarts of silver primer. We recommend 2 coats of the silver primer, then topcoating with another paint. If just using the silver alone, 3 coats is recommended. Given that, I would say you need a couple more cans of the silver MasterSeries. Pretty much all of the work I do I try to spray on the coatings. Both the AG111 and silver primer, I thin with urethane reducer about 15 percent, and spray it out of a cheap Harbor Freight $14 spray gun. I sandblast the items, or sometimes the entire car and chassis, then spray on the MS. Two coats of the silver, then seam sealer if needed, then the AG111 topcoat when doing the chassis. When I do the body of the car, I sandblast everything, apply the 2 coats of silver primer, then seam sealer. Then it goes to the paint shop where they apply filler on top of the MS silver primer as needed. Then they scuff the entire body, apply Dupont products gray .
primer and proceed to apply single stage Dupont products.

i have a friend that works on VWs of his own in the St Augustine area and he sprays the MasterSeries products on a regular basis. You need to pick the lower humidity days if possible and you might have to wait until the humidity tapers down a little where you live.

When you open those cans, mix the product , pour it off, and return the lids to the cans asap. Should last in the can a few weeks. Remember the more you open and close the can, the more moisture and air get introduced into the paint , and the quicker it will set up. The AG111 can be used in small batches. Just mix 2 parts of paint to one part of hardener. It can be 2 spoonfuls of paint(part a) to 1 spoon of hardener(partB). Or if you use a measuring cup, 2 ounces of A to 1 ounce of B. Once you mix the two parts together you have a pot life of about 6 hours before it starts hardening.

Your prep process sounds OK. The metal prep we sell, you apply it with a rag , sponge, hand sprayer. Then within a few minutes wipe it with a clean rag or paper towel. Then let it dry for most of the day. Then the next day ready for paint. Our stuff doesnt require washing it off. Read the directions on what products you are using for best results. Hopefully I have answered some of your questions. Thanks for using our products. Chuck

Emil, My Harbor Freight gun has a tip that is 1.4 and that has worked fine for the silver primer, thinned 15%. Now the AG111 is a thicker paint, but if you have a 1.8 tip , which is a primer gun size tip, that should work OK. Once again thin the paint 15%. If it still doesnt want to work, go a little more on the urethane reducer. I wouldnt recommend on drilling out the tip. I think it might be an easy way to screw up a gun. Chuck

I know the above passages do not address your "brushing it on" question but the information may be useful to you. Reach out to Chuck via PM. He will give you a straight answer.

You can apply that AG111 with a brush with great results. If you put it over the MS silver primer and that primer has been on for more than a couple of days, I would get some 320 grit sandpaper and scuff up everything. Use a fine bristle brush and try a small area. If you are getting some brushmarks, use a little of our reducer and thin perhaps 5% and see how it brushes then. If still brushmarks or the brush drags, add a little more reducer. If you dont have our MasterSeries reducer, the paints are urethanes, so medium grade reducer is OK. If using something like foam brushes, get the best foam brushes you can find. Using cheap ones, the foam will start flopping around within a couple of minutes, pieces of foam will come off into the paint , and you will be totally frustrated. I have been to Ace Hardware stores and TruValue Hardware stores and actually found some decent foam that didnt fall apart so quick. They will go south but it will take longer. Ive used 2 inch wide with good success. Those foam brushes are actually made in the USA and the label is Gem. Seen some on Amazon and Ebay , but you need to buy a small quantity. The AG111 can be brushed out for a flawless finish and dry super hard. Mix a small batch 2 to 1 with the hardener and try some of the above. ChuckP

I did both sides of my pan, and wheel arches and trunk with Silver primer and AG-111 with foam brushes. I stopped using the reducer, and used extra hardener with the AG-111 because I was getting runs on the vertical surfaces. I was more than pleased with the results I got.

Chuck:
I tried MS primer (silver) with a sprayer and it was a disaster.
I used the Ace Hardware "Kleen Strip VM&P Naptha" as a reducer, at LEAST 10% as suggested, a sprayer and a 1.8mm tip from HF, and I could NOT get the darn stuff to come out.

135 psi pressure at tank, 40psi-60psi at gun, and just nothing.
What do I need to do?

I usually thin that silver MasterSeries about 15% or sometimes even more. The current MS silver seems to be a little more on the milkshake side of consistancy. 40 psi at the gun is more than enough. I use a Harbor Freight 14 dollar gun with a 1.5 tip and it works fine. Put a little reducer or thinner into your cup and try spraying that. See if thinner actually comes out of the gun and it isnt plugged up. Also after you thin the MS , run it thru a paper paint strainer. Sometimes there are some clumps or chunks that can give you issues. Im thinking you need to thin it a little more. Your pressure is OK, gun tip size is OK . Chuck

Success!
I drilled out the 1.4mm nozzle on the purple HF spray gun to 5/64ths, thinned at ~ 15%, and she turned out great. Now to seal and recoat!
