Can this be applied over existing silicone

I always clean old stuff of first then apply

Can you use for roof rail sealant for VW micro camper(caddy)?

I would use it as I repaired my roof to gutter seam with it and have had no issues yet and that's a couple of months ago

We need to reseal our whole motorhome around all the joints etc. How many packs of this would we need? The Moho is 7.5m long. Thanks

Depends upon what size gaps you’re going to seal. Very sticky, I’d start with two and smooth it in. You could always get more if needed.

Can silka522 be overpainted

Overpainting. Sikaflex®-522 can be best painted within the skin formation time. If painting process takes place after the sealant has built a skin, adhesion could be improved by treating the joint surface with Sika® Aktivator-100 or Sika® Aktivator-205 prior to paint process.
