so i just wanted to update alittle bit last night i worked on cleaning up the floor pans more to get all that nasty tar stuff off and so heres what i did

using heat gun and a putty knife i just heated it up and slided the puddy knife underneath and it brought up the tar like butter it was so easy and quick!







and you can see the hole im dealing with on the passenger side the driver side has small holes in it but nothing bad... i should just replace both while im at it i think

[theman53]

I hate you a little for this. I never thought of the heat gun. I used a wire wheel on a grinder, it probably took me 8 hours of work time to get it a good surface to weld to.

Nice work BTW.

I saw someone just dumped pellets of dry ice on that stuff and it came out in cracked up pieces with no mess.

[theman53]

Whomever that is, I hate them a little too.

[vw-tim]

haha dont hate just learn for next time yeah i honestly did both rear sides in about an hour.... im gonna try and get all the upper tar off the fire wire gonna get rid of it all!

[vw-tim]

okay so got a question so i got the engine out and just wanting to clean up the engine bay i figure now is the time to do so i was wanting to just re paint it clean it up some. anyway i was thinking of sand blasting it but have read some stuff not to go with sand because its hazardous and it heats up the metal too much so i was thinking of making this and doing baking soda?

and heres a pic of the bay im gonna remove the steering rack and shift linkage as well just havent gotten there yet.



what do you guys think is best way to do this?

[CarlosA]

Wow, was that entire front end welded onto your car, or is that the blasting?



So I know its a little late but wanted to post this here anyway for future reference:

Looking at the surface corrosion on the bulhead and up on the top of the inner wing where the outer wing bolts compared to the corrosion on the green front end i would hazard a guess that it has been replaced. 

I am not sure that soda blasting will remove surface corrosion unless you have a pro do it, home blast cabinets and single phase compressors would struggle unless you use grit.

I use aluminium grit on delicate parts and it is a great halfway house between the steel shot and soda.

Will you be doing it yourself?

so just alittle update here i started sandblasting the engine bay and it works pretty good it just slow process anyway heres a pic i should have this thing blasted in next couple days if i keep at it ha

[nathantheengineer]

That is working well, blasting is a slow job! 

Can definitely see that weld on the inner wing now.  When was the front end replaced?

i have no idea and yeah its a slow job but itll get there eventually ha is there anything i can do about that weld on the wing i was thinking of grinding it down i just want to to be alittle smoother but will that compromise the strength of it? i would like this engine bay to be all smooth and appear to be one solid piece if possible once i paint it and everything ha

I would grind the weld down very carefully, then apply the necessary bondo to smooth it out. If you don't grind down to the base metal of the weld, then (provided there's good penetration!) it should be fine with a little surface grinding. Check the other side of the weld to make sure there's adequate penetration, then go for it.
Other than that, all I can say is that I wish I had a sandblasting setup myself--looking forward to the final result. Should be good stuff for ya
