Proven Windshield sealant

Some 11 years ago I used the best SIKA Windshield glazing/sealant available to seal the windshield of my 79 Moho. I had a few issues that require a thick application in 1 area. The SIKA sealant held up for 11 years and still is going strong. I went back to the same Glass company and ask for their best Polyurethane product from SIKA available now to reseal the windshield of my 345. They sold me SIKA Tack Moveit and I applied it today
After carefully removing the old sealant, I used my airhose to blow any dust and dirt out from under the gasket. Then I cleaned the glass and the rubber with Lacquer thinner and applied the masking tape to create a appr 3/8" wide strip, half rubber and half glass. The sealant needs to be applied rather fast and is even harder to use than Vulkem. It can be smoothed out with paint thinner for appr 5 to 10 minutes and then should be left alone. The tape should be removed immediately after application.
I recommend using gloves during application, since hardly anything works to get it off your hands.
This makes for a nice clean look that will last a long time.

Peter,

Great tip! I've been thinking it wouldn't be a bad idea to put some sort of sealant on the windows of our 310 and Argosy.

Wouldn't you know, one more thing to add to the list

Thanks!

Brad

Rubber and Aluminum

Do you do anything with the aluminium skin to rubber joint?

My aluminium/rubber seal is tight. But when I purchased the tube of Sika, the technician told me to "roughen up" the aluminum slightly after taping it off as I did with the glass/rubber. This is not really needed , but will improve the bond. There are small pads available that contain glass particles to prep certain surfaces. A professional auto glass shop has those pads, if you ask for them.

Peter,

I've searched everywhere online and can not find any place that sells the Sika Tact MoveIt product.

Any suggestions?

Thanks!

Brad

I purchased mine from the local Glass company, but it was not an item they had on display. I had to ask about it very specifically.
Good luck!

Thanks Peter. I'll try calling them today.

How many tubes did you use for your windshields? I have two motorhomes to do so I want to make sure I get the appropriate amount.

Brad, depending on the thickness of your bead and if you do the glass only, 1 tube for both if you do them the same day. Once you crack the seal, it will get polluted at the tip even if you try to stick something in it (fast dry). It is very stiff, so if you can set tube in the sun for a couple of hours it will help.

So in other words I better buy some extra tubes cause I'm likely going to need them

Since we're heading into winter it sounds like I need to wait for a nice sunny day, have the front of the motorhomes face south and do it in the early afternoon.

Thanks again!

Brad

Well, I tried James Town Distributors and they referred me to another company who said they don't carry it and suggested I google Sika automotive, so I did. It's weird that the Sika website describes the product but I can't find anyone that seems to sell it.

Richmond doesn't have a lot of Automotive glass businesses so till now I hadn't bothered to check them out. I think I'll stop at the two that show up in the phone book and see what they have to offer.

Just finished sealing my Argosy windshields with the stuff Peter mentions above. I can vouch for the fact that it is fast drying

I do have a couple of recommendations that might make things a little easier for the next person. One of the mistakes I made was to tape off the entire windshield at one time. The problem with this approach is since it is such a fast drying product you can't remove the tape easily since it overlaps with the top and bottom (or sides) of the gasket. I calked the top edge of the windshield and smoothed and then realized that I couldn't remove the tape until I did the bottom side of the gasket. This led to me always trying to play catch up with trying to remove tape.

To make matters worse my caulk gun wouldn't work with this style tube. The tube appears to be made of aluminum and the first caulk gun I tried to use apparently was a tight fit inside the tube. I was having to squeeze so hard just to get a little bit to come out the nozzle. (I wonder if Peter's ears were burning while I was trying to squeeze the trigger!) I then ran back up to the house and got a different caulk gun which worked flawlessly. I never had that sort of problem before. Unfortunately this delay allowed the top edge that I started on to set up prematurely.

I ended up with a couple of small spots that I will need to redo because I couldn't keep up with the caulking, smoothing, tape removal in a timely manner.

My suggestion is to tape so that you can do the insides seams of both windshields first. Caulk one whole inside half, smooth and remove the tape. Then move to the other windshield and repeat. Once both are done take a short break to let the sealant set up, doesn't take more than a half hour and it seems to be totally cured. Now go back and tape around the outside edges of the windshield. Once taped caulk one edge, smooth it and then caulk the next edge. Now go back and remove the tape from the first edge. Repeat this process until you're done.

I guess you could say I used the Argosy as a test bed since the 310 needs the same treatment.

Hopefully the second time around will go a little smoother!

Brad, Did you purchase the SIKA Tack Moveit from the manufacturer? This is a great link! I want to seal the windshields on my 24' before the weather cools. Thanks, Greg

Greg,

I ended up purchasing mine from the same place Peter bought his in Austin Texas. Unfortunately I don't remember the name of the place. Hopefully Peter will chime in with the name and possibly a phone number.

The SIKA Tack sure seems to be a good product. The important thing I found out is to plan ahead and work FAST and have mineral spirits with plenty of rags available when using it! Oh yeah, get some nitrile or latex gloves, you'll be glad you did

Brad

Brad,
I have still not been able to locate the Sika move it. Any chance you can find the receipt and hopefully come up with a phone number? Thanks, Greg
