JJC Posted January 16, 2014 Author Report Share Posted January 16, 2014 Laughingly called drain holes. Stuart. uFor draining in I guess! I dropped a bolt when fixing the backlight on the 4 it went right down the B post through the hole and into the sill. Where it rattled. Just wondering whether or not the bottom of the A and B posts should be sealed to the sill to prevent water/mud ingress. JJC Quote Link to post Share on other sites
stuart Posted January 16, 2014 Report Share Posted January 16, 2014 When fitting new sills I always seam weld the bottom of the "A&B" posts and then lead over the bottom seabtions and put the seam lines back in after. That way you dont get water in and you dont get paint cracking.It also stiffens the shell up.Also make sure that the "A&B" posts are seam sealed all round right to the top. Stuart.

RogerH Posted January 16, 2014 Report Share Posted January 16, 2014 The 'A' & 'B' posts can gather condensation so needs somewhere to drain. The sill area is vented; so any water going can come out. Remember to waxoyl all the closed areas Roger Quote Link to post Share on other sites
JJC Posted January 17, 2014 Author Report Share Posted January 17, 2014 Remember to waxoyl all the closed areas Roger I've waxoyled this car for decades. When I cut the outer sills off there must have been a kilo of solid waxoyl each side. Perfectly preserved a very early bodge. Incidentally local expert advice is not to waxoyl until painting is finished. JJC Quote Link to post Share on other sites
