wicked

I'd imagine between the two, polyurethane would be good to use.

i disagree silicone should work better.


-Borsty

make any suggestion anything that you think would work, more info im looking to permanently fix this ie something that wont just fill the hole but will also recreate those welds that seem to have rusted or separated(not sure since the metal makes it impossible to see)

wicked

You said caulk.......


uhhhhhhhuhuhuhuhuhuuh.............

caulk..............

..... *isnt going to give the above poster the generosity of an insult*

ok fixed it, used poly, ill see how it holds up to high water pressure tomorrow.

wicked

oh and they werent rusted the welds did but the wheel wells were fine, the welds just separated from the look of it after i cleaned it

if not, liquid nails maybe?
bondo, fiberglass, peanut butter?

Eye wub you!!!!

haha. peanut butter!


i suggest fiberglassing it...


...

fiberglass would have had no way to stick to it that i know of. bondo might work, didnt get a chance to work on it today, but i hopefully will this week as well as get my false floor started now that i hopefully got the leaks all fixed.

wicked

bondo will need a way to grasp ahold just same as the fiberglass... drill a few-to-several pinholes around the area and that'll give the bondo a place to fill into. it's not the best in quality nor the most effective but it is cheap, quick and somewhat long lasting (given a little kid doesnt' come along and kick the eff outta the EXACT spot you decided to bondollio)

sand and smooth as needed.

If you are looking for the original seam sealer material used in our cars you can buy it from GM still comes in a box as a kit. Good to seal up raw metal and welded surfaces prior to painting.

alit of @!#$ jb weld

You can buy "seam sealer" from any body shop supply place and from some automotive stores. 3M, au-vee-co, and others make it. If the metal can be cleaned bare, you could actually use 2 part panel adhesive to seal and provide strength. Similar adhesives are being used today to hold vehicles together.

I think silicone sealer tends to peel with time. I've worked at camper and RV places, and I currently work for a bus company. Any time we use silicone, seems like we're re-sealing the joint within a year or so. Plus, paint and undercoat don't like to stick to silicone. I'd choose poly, too.

maybe this will be good for future reference
