Welding drain holes, Questions


Recommended Posts

What works best, do you put in the plates on top of the holes or underneath when you butt-weld them in?

Where can I get that 3M 5200 seal sealer, or do you recommmend the stuff that Por15 has?

Using a micometer, what would be the decimal read out for the various gauge of sheet metal (20, 18, 16) more curious than anything

If the floorboards have no damage (still have the factor primer on them), would it be overkill to cover them with Herciliner before laying over FatMat?

What do you all prefer, acid etched primer (green stuff) or Por15 treatment process?

Again, I can not thank you enough, maybe one day I can figure out how to send pics using that PhotoBucket system.


The question is not that we broke a few rules or took certain liberties with our female guests.

We did ;)

By drain holes you means the approx 3-4" holes in the floorpan? Why weld them? clean the up with a wire wheel and 'glue' them back into place, they twist to lock in place - do this with wet paint, POR-15 or your fav primer - or seam sealer.

Seam Sealer if you only need a little ask your local panel shop, it might only cost you a 6 pack :)

For 'gauge' thickness see here:


POR-15 or acid etch? Over factory primer I would just use a normal primer.

With loading pics - open a post in the TEST forum (just for testing - thats why its there) - below where you type is the 'Add an Attachment' field, click 'Browse' to locate your file, then click 'Add Attachment' - job done.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
