So I have two floor panels that screw down (under the driver and passengers feet). Was wondering if I could use blackjack to seal these when screwed down. From the looks of it won't be a REALLY tight fit along the contact points. I'm thinking that blackjack would fill a gap of 1/8" or so and be flexible and waterproof. Anybody got comments or other suggestions?
I just did the floors in my buick and used seam sealer on the welds/joints on all the panels. It is cheap and u can get it at autozone. Make sure you follow directions, some kinds require a primer before you put it on. I used some by 3M and it was good to go on bare metal. http://www.autozone.com/autozone/ac...&fromString=search&itemIdentifier=167027_0_0_
while repairing a skylight on my RV i thought about using that sealant on my hotrod and the roof seams on my 67 chevy p/u it comes in a caulking tube and runs about $9.00 a tube. some leaked out of the empty tube and adhered very well to wood & cardboard also, buy it at an RV center, just fyi
I have a similar situation where I have floor boards to screw down to a sub frame. I plan on using a polyurethane caulk from the home center. I belive your automotive ( Napa/3m products) type seam sealers/caulk are a urethane product also. The stuff from the home center is good for fifty years, sticks good to metal or wood, cleans up with mineral spirits and takes paint very well from my experiances. Aproximate cost is about $10 a tube. DO NOT USE SILICONE PRODUCTS !!
I always have a gallon can of wet or dry waterproof roofing tar/sealer around for sealing (from bottom -up) seams. It hardens to something like undercoating. No one ever seems to believe me about how good that stuff is
No on the blackjack,you might need to remove these panels in the future then you will be cussing yourself for the mess you made. Get the seam sealer like suggested and do it right.
