Many of the home type sealants really do not last long on the camper application when doing siding sealing. The flexing of the camper creates flexing that does not occur on a house.
If you are talking about a leak between the siding and the front window frame, I use this product, Proflex RV, https://www.geocelusa.com/product/pr...xible-sealant/
They sell it ay many places that sells RV parts. Pic the color that matches your camper.
A few tips on applying it:
- Make sure you clean all the dirt off stuck to the old putty tape. That black yuk will turn gray when you get all the dirt and mold off.
- When smoothing it out, cut the tube tip small. Gun it on as good as you can.
- Using a soapy wet finger, tool it out, (spread it out) smooth it out. Keep your finger wet and it will smooth out nice.
- Do not apply on a hot summer day, it dries to fast.
- Only apply about 2 to 3 feet length of caulk, tool it out, then apply more. If you put all the caulk on an entire front window at once, it will tack up too much, drag, and make a mess when you start tooling it out.
You did not mention if the leaks was on the glass to metal frame, if it is glass to frame, Proflex RV does come in clear also and is glass rated. I use Parbond on glass sealing, I find it here at PPL. https://www.pplmotorhomes.com/parts/...-clear_38-8722
While I have not used the Proflex on glass, the product is very good and if Geocel rates it on glass, if I could not get the Parbond, I would try it.
Hope this helps
