Hey Doug,
Everyone in the industry that I have talk to have said to use Sikaflex 252. You can get it at International Bus Parts in Florida. 1-800-468-5287. Give them a call. Great bunch of people that don't mind answering questions. I found it on the internet and they have a dealer location on their web site. A little expensive, but everyone says it works I haven't used the case I got yet. Good Luck Larry (Oregon)

I can endorse Sikaflex. We use it all of the time. 3M 5200 also. Drying time is 24-48 hours for metal to metal and read the instructions. They are expensive but they really are the best. Mike

U can get Sikaflex locally if u look around. U can also go to any Loews or Home Depot and buy a construction grade urethane adhesive, which is what Sikaflex is, for a lot less money and works just as good

Make sure you get some instructions on Sikaflex. There are none on the tubes of adhesive. Call their tech dept.& they will e-mail

There is a video advertised here on BNO at http://www.busnut.com/seecs.html titled "Bonding Steel Over Window Openings" that shows how one coach had the openings covered using Sikaflex 252.

hey jmaxwell if what you say is truew it will save me a lot of money to just use a constuction grade urthane adhesive does it say on the sikaflex that it is actually a urathane or doesnt it say on the tube if it does im just going to use the constuction grade stuff i think how much is expensive and i cant help thinking i can hear someone saying dont be a dope use the good stuff who is that

I run a commercial sign shop building large aluminum signs. We bond aluminum to aluminum and steel to steel all the time here with Lord Adhesives 2-part adhesive products. This stuff is expensive and has a very limited working time but the bond is really amazing, I have never been able to seperate the parts. We had a U.L. inspector test one of our signs and the metal failed before the adhesive did. I have heard great things about Silkaflex too.

From the BTDT Department, there is absolutely NOTHING available at Lowe's/Home Depot that is comparable to 5200 or 252.Even their 50 yr. urethane sealant/caulk is only good for two years, and when you try to get it warrantied they only offer to replace the tube. Lots of time and money associated with replacing the junk they sell. Cheers...JJ
