MG TD TF 1500 - A good undercoat to use.

At this time there is a thread about problems removing undercoats. I'm interested in looking into that which is a good undercoat to use. When I painted Lazarus some 20 years ago I didn't undercoat the fenders. I certainly regret that now. What's worthwhile applying? Bud

There are the rubberized aerosols. I believe 3M has a good product Go to your local automotive paint supplier and get there recommendations. Spray on bedliner is another option which can be bought in aerosol forms as well from the same paint shops. I’m not talking about body shops but the actual paint supply stores. Keep in mind it will add weight to the wings which may cause other issues such as stress cracking of the thin sheet metal. Probably more likely on the front wings around the headlight mounts, spot welds and tight bends in the inner splash aprons. I would use it very sparingly while masking or avoiding mounting point hardware altogether

I can tell you what I don't recommend. That would be the rock guard coating as used back in the 80's on the lower panels of new cars. I did the undersides of the TF and the TD with it and plenty thick but it didn't protect it against the expected rocks on the underside. I used some spray on undercoating from NAPA on the MGB...not all that impressed with it either.

When I found Lazarus he had the OEM black primer covered by the original Autumn Red, covered by the dealer-applied white paint, covered with a coat of red paint applied with swabs. I totally disassembled the tub and had all of the parts bead blasted before taking them to the bodyshop for painting. I provided the Martin Senour tinted primer, plus the Martin Senour Autumn Red color and the clear coat. The body shop screwed up and wasted much base coat where it didn't belong and wound up using an 'almost' Autumn Red to finish the job. Learned later that they did my work in the afternoons after their notorious liquid lunches.
Didn't take long before bubbles began to show up on the upper sides of the front fenders from road rash on the under sides. He really didn't take kindly to being driven 12 months per year in New England. He deserves being repainted, but I'm not going to strip him again except where I'll have to. Still hunting for a competent, reasonable, painter in the Atlanta area. Bud

Having a hard time understanding this statement:

"Didn't take long before bubbles began to show up on the upper sides of the front fenders from road rash on the under sides."

Do you mean that rock impacts on the underside caused the sheet metal to be raised and then the top coat of paint separated where these "mounds" occurred? If so it sounds like they really did a bad job of paint preparation and/or the wrong type of primer. You may want to consider one of the epoxy or more flexible primers that have better adhesion and give a bit when impacts occur.

Chris, I haven't excised any of these 'bubbles' to ascertain their depth. I'll get some images later and show them tomorrow. The primer was from the same Sherwin-Williams paint series as the base and clear. There's little question but that the preparation was atrocious. The shop want out of business shortly after my job. At the time I owned a NAPA store and they were a customer. Bud
